Even if the subject of kilowatts no something friend think about every day, it’s absolutely something the affects your day-to-day life. Girlfriend see, a watt is the straightforward unit that measurement supplied for electric power. The ax “watt” originates from James Watt of Scotland, an engineer, entrepreneur, craftsman, instrument maker, and also scientist that is often referred to as the dad of the industrial Revolution. Among his many notable accomplishments was roughly 1775, when he designed the Watt steam engine. Today, vapor turbines in ~ thermal power plants usage this same technology to transform thermal energy into mechanically energy. We measure that electrical power in kilowatts.  

In this guide, we take the complex subject of kilowatts and simplify that into much more relatable terms. Here, you’ll gain a better understanding that what kilowatts are, to add we’ll cover things choose what us measure in kilowatts, just how we convert and calculate kilowatts, and how kilowatts differ from kilowatt-hours, megawatts, and gigawatts. 

What Is a Watt? What Is a Kilowatt? 


Before we comment on kilowatts, let’s take it a second to talk around watts (W). Watts space the simple unit of power provided to measure up electric, thermal, and mechanical power. One watt is same to one joule, as well as one volt-ampere. Every one of these state measure electrical power.   

Now, let’s gain into a much more detailed description of what a kilowatt (kW) is. Most simply, a kilowatt is another term supplied in the measure of power. Many frequently, we usage kilowatts to measure up residential and also commercial power.   

Keep in mind the the prefix “kilo” method one thousand. It may be simpler for you to remember that one kilowatt equals 1,000 watt of electrical power as soon as thinking that the prefix’s meaning. Because that example, a microwave through a 1,000-watt label calls for 1,000 watts worth of strength (or 1 kW) come work.  

How carry out You transform Watts into Kilowatts? exactly how Do You convert Kilowatts to Watts?  

The conversion of watt to kilowatts is simply as straight-forward as you may have guessed. We find the power in kilowatts P(kW) by splitting the power in watts P(W) through 1,000. 

Here’s the Formula for Converting Watts right into Kilowatts: 

P(kW) = P(W) / 1,000 

For example, if you wanted to transform your 1500W dishwasher come kilowatts, friend would carry out the complying with calculation:  

P(kW) = 1,500W / 1,000 = 1.5kW 

Here’s another means to think of the that may make the mathematics easier. Add a decimal point at the end of your totality number. In this case, that 1500. Then, because there room three zeros in 1,000, i m sorry is the number you’re dividing by, you will relocate the decimal suggest three digits, or three spaces, come the left. You finish up with 1.500, or 1.5. This trick provides it really simple to convert watts right into kilowatts v some fast mental math. 

Here’s the Formula for Converting Kilowatts into Watts: 

Since we recognize that one kilowatt is identical to 1000 watts, us reverse the operations over to deal with this equation.  

1kW = 1000W  P(W) = 1000 × P(kW) 

For example, if you recognize that your dishwasher supplies 1.5kW, friend would perform the equation below to uncover that her dishwasher is a 1500W appliance or calls for 1500W of strength to work.  

Convert 1.5kW come watts:  P(W) = 1000 × 1.5kW = 1500W 


How plenty of Kilowatts space in a Megawatt?   


We usage megawatts once measuring power on a much larger scale. If you want to know how much strength is produced by a strength plant or exactly how much electrical energy is compelled to power an entire city, friend would usage megawatts. Because that example, a common coal power plant is roughly 600 MW in size.  

To proceed along the course of keeping things simple, use the same formula used above to convert kilowatts come megawatts (MW). Why is that? Well, since 1,000 kilowatts are equal come — girlfriend guessed that — one megawatt. 

Here’s the Formula to convert Kilowatts come Megawatts: 

P(MW) = P(kW) / 1,000 

This formula also method that if girlfriend would choose to transform watts come megawatts, you have actually to include three much more zeros to her equation. The strength in megawatts P(MW) can be uncovered by dividing the power in watts P(W) by 1,000,000. 

Here’s the Formula to convert Watts come Megawatts: 

P(MW) = P(W) / 1,000,000 

For example, if you transform a 100-watt light bulb to megawatts, you will carry out the complying with calculation:  

P(MW) = 100W / 1,000,000 = 0.000100MW 

How many Megawatts are in a Gigawatt? 

Suppose you’re searching for an even larger measure unit. In the case, you’ll want to use gigawatts, which we use to measure exactly how much power big power tree or number of plants have the right to generate together. In 2012, the complete capacity of united States electricity generating tree was about 1,100 GW.  

You’ve likely noticed a pattern developing here. In the case, you may have actually a great idea as to what the formula is for converting megawatts to gigawatts (GW). If girlfriend guessed that there are 1,000 megawatts in one gigawatt, you would certainly be correct. That fun fact method that there are 1,000,000 kilowatts in one gigawatt and 1,000,000,000 watts in one gigawatt. Whew! 

What are Kilowatt-Hours? space Kilowatt-Hours various Than Kilowatts? 


 Now, here’s where things can get a little confusing. A kilowatt-hour (kWh) is a measurement of just how much power is used. However, this is not actually the exact same as measure the number of kilowatts you usage per hour due to the fact that power and also energy are not the same. Instead, a kilowatt-hour actions the quantity of time, or the amount of energy, the takes to usage one kilowatt that power.   

The amount of power used if a 1,000-watt appliance runs because that one hour is equal to one kilowatt-hour. The reduced the wattage an object has, the better.   

Here’s one example: If you to be to usage a 100-watt light bulb, it would wield one kilowatt-hour of power after 10 hrs of use. But, if girlfriend switched come a more energy-efficient light bulb that only requires 40-watts to produce the exact same amount the light, it will certainly take 25 hrs to usage one kWh of energy. Imagine the energy savings you could achieve by convert out every one of the lightbulbs in her home.  

Just like measuring strength consumption, as soon as you calculation the lot of energy used or created on a bigger scale, girlfriend would use megawatt-hours (MWh) or gigawatt-hours (GWh).  

How execute I calculation the Energy intake of an electrical Appliance? 

How Is My energy Use in Kilowatt-Hours Calculated?

Much prefer one kilowatt is same to 1,000-watts of power, one kilowatt-hour is equivalent to 1,000-watts, or joules, of power use end one hour. If you wanted to transform watts into kilowatt-hours to find out how much power your coffee machine consumes each day, you would certainly multiply the power usage in watts by the variety of hours used. Then, divide that number through 1,000. 

Here’s the Formula for Calculating Watts into Kilowatt-Hours: 

kWh = (watts × hrs) ÷ 1,000 

For example, to find the kWh the 1,200 watts for 3 hours:  

kWh = (1,200 × 3) ÷ 1,000  kWh = 3,600 ÷ 1,000  kWh = 3.6 


How perform I convert My Energy intake of Kilowatt-Hours right into Watts? 

Suppose you were interested in doing the turning back to identify how many watts her coffee device is, based upon its kilowatt-hours. In the case, you might easily carry out so by making a few simple adjustments come the formula.  

For this conversion, multiply the energy used in kWh by 1,000 to find the energy usage in watt-hours. Then, you have to divide that number by the variety of hours you supplied it. 

Here’s the Formula for Calculating Kilowatt-Hours into Watts: 

watts = (kWh × 1,000) ÷ hrs 

For example: let’s discover the watts of strength for 3.6 kWh of energy used in 3 hours.  

watts = (3.6 kWh × 1,000) ÷ 3 hrs  watts = 3,600 ÷ 3 hrs  watt = 1200 W  

What does One Kilowatt-Hour of electrical Energy Cost? 


Most utility suppliers calculate your electrical power bill based upon how numerous kilowatt-hours, or systems of power you use each month. Since the scientific unit of power is measure in joules, you will often see your power usage noted in joules ~ above your electrical bill. Remember, one joule is equal to one watt. If you can transform watts to kWh, you can predict just how much the might cost to operation your various electric appliances and also devices. 

In 2020, Idaho residents paid the lowest average power rates in the U.S. At 9.67 cents per kWh. In too much contrast, residents in Hawaii payment the most, v their median 2020 electrical power rates coming in about 28.84 cents per kWh. 

How do I calculation the usage of an electric Appliance? just how Do I estimate What My electrical energy Bill will Be? 

Let’s use the national average rate of around 13 cents per kWh to calculate exactly how much it costs to power a 100-watt light pear every hour. Because it takes 100 watts of strength to job-related — to convert the strength in watt to kilowatt-hours — you will multiply 100 watts by one hour. Then, you’ll division by 1,000 to discover the energy intake in kWh.  

Energy = (100 × 1) ÷ 1,000  Energy = 100 ÷ 1,000  power = 0.1 kWh  Hourly cost = electricity price per kWh ÷ energy use in kWh  Hourly expense = $0.13 ÷ 0.1 kWh  Hourly price = 1.3 cents 

If electricity costs 13 cents per kWh, then a 100-watt light bulb will cost 1.3 cent for every hour the it’s on. Most electrical bills room calculated monthly. To estimate your monthly costs, you deserve to follow this steps:

Estimate how plenty of hours every day you use that light bulb on average. (Let’s say it’s 5 hours).

Multiply the irradiate bulb’s watts by the average number of hours you usage it day-to-day instead the the one hour used in the formula above. (Let’s say your light pear is 60 watts, so the you would certainly calculate 60 watt x 5 hours).Solve the equation over using her light bulb’s really wattage and the actual average variety of hours you usage that light pear per day. (60 x 5 = 300 ÷ 1,000 = 0.3 kWh). Multiply her answer through 30 to get the monthly typical kWh for the light bulb. In this case, $0.43 x 30 job = $3.90. That would cost you $3.90 per month to leave a 60-watt light pear on because that an typical of 5 hours per day, every day.  Repeat this equation for all light bulbs, appliances, and other electrical devices in her home.   Add increase the complete to uncover your estimated monthly electricity prices in kilowatt-hours. You might be surprised to view how rapid it all adds up. 

How many Kilowatt-Hours does the average U.S. Family Use per Day? 


Now that you know all around how to calculate the kWh of energy consumption you use, it can be exciting to to compare your power use to rather in the united States. The average house in the U.S. Spend 887 kilowatt-hours (kWh) of power per month in 2019, which breaks under to virtually 30 kWh every day. If you’re curious to check out where friend stand contrasted to rather in your specific an ar or state, inspect out this data detailed by the U.S. Power information administration. 

How countless Kilowatts need to a Generator be to run a House? 

If you live in an area prone to weather the could result in strength outages, girlfriend can offer yourself a small peace of psychic by investing in a generator. Freezers, lights, refrigerators, and well pumps are simply a couple of of the appliances you could keep running during a strength outage.   

The most crucial household equipment can be run with a 5,000 come 7,500 watt rated generator. If girlfriend would favor your whole house to continue operating, girlfriend will likely need to walk larger. If you have fewer appliances, friend may be able to get away with something smaller. Identify the wattage the your vital appliances will help you figure out what size generator you will certainly need. 

What’s the Difference between Watts and Amps? 

Watts and amperes, additionally known together amps, space both units supplied to measure electric power consumption or production. Every electronic tools have their energy consumption provided on their brand in either watt or amps. If the label on your an equipment lists amps, you have the right to calculate the wattage by using a basic formula. 

Here’s the Formula because that Calculating Amps come Watts: 

Wattage = Amps x 120  


For example, if you have a 120V an equipment with a 20 amp label, that’s equivalent to a wattage the 2400. In equation form, the is: 20A x 120V = 2400W 

What Is the Kilowatt-Peak?  


Kilowatt-peak (kWp) describes the rate a system have the right to generate energy during its height performance, i beg your pardon is once it’s functioning at its maximum capacity. We most commonly use kWp for solar power systems. This systems room labeled v a rating in kilowatts peak (kWp) so the consumers can compare the output capabilities and size of various photovoltaic panels.   

A 2 kWp device will develop 2 kW of electrical power only during the brightest sunshine as soon as all conditions are at your best. Conventional modules take roughly 6.25 square meter of roof an are for every kWp. Greater efficiency modules usage only 5 square meter of roof space. 

How technology Is transforming the power Industry 

There’s no inquiry that modern technology has enhanced by leaps and also bounds over the years. Points aren’t any kind of different in the energy industry. Let’s take it a look in ~ two terrific examples. 

How lot Does It price to fee a Tesla? 

Tesla has actually been around since 2003, but now that electric cars room becoming much more common, they’re also becoming much more affordable. As gas prices space going up, the cost to charge electrical vehicles is walking down. Take it a look in ~ this example which describes how much it expenses to charge a Tesla model 3 in ~ a home charging station:  

The battery capacity is 75kW, and our present average power rate that we’re walking to usage is 13 cent per kWh  This method that your charging price is equal to 75 x $0.13 = $9.75 for a finish “fill up” the will get you around for around 240 miles.
