Speed is the unit of measurement for the object’s movement per time unit. It commonly simplified as km/hour or m/s. The more distance it passes and the shorter the time it takes, the higher the speed of that particular object.

You are watching: What unit is used to measure speed

Measuring the speed of a particular object is important for us. When you are evaluating the performance of a car, one aspect of consideration is the speed. When you are driving, if you run the car over speed, you may encounter some unexpected thing. By having the speed measuring device on your dashboard, you could control your car speed.

When dealing with a machine, monitoring its performance can be done by observing the speed. Since this machine is spinning, we are not using the typical km/hour or m/s unit of measurement but in this case, we use RPM. RPM is the acronym for Revolutions per Minute. Simply, how many spinning it takes per time unit. Let’s say it’s 1000 RPM. That said, it spins 1000 times per 60 seconds.

There are a huge number of devices that we use to measure the speed as their application is wide and everywhere. This page contains a list of speed measuring devices that we could find in our daily life.

Top 7 Speed Measuring Devices

1. Speedometer (to Measure Car Speed)

Who doesn’t drive car today? None. Everyone knows this pretty stuff. And speedometer is the most bolded instrument panel that we easily notice on the dashboard. This measuring tool is installed directly in the system. It gives a real-time reading of the car speed. The same thing happens to other transportation as well such as bus, truck, bike, motorcycle, etc.

2. Tachometer (to Measure Angular Speed)

A range finder is like a binocular, but it’s able to read the distance between the device and the object being watched. It’s not weird that an advanced range finder comes with a speed meter feature. It allows you to observe a moving object while it’s displaying the object’s speed.

Conclusion

Those are a variety of speed detection devices that we could find relatively easily in our daily life. Actually, there are a lot of devices that we haven’t mentioned yet. They work by using the principles in Physics. Furthermore, they make our life easier and more accurate. Especially the anemometer in the weather station, it helps us to warn people or predict the water so that we can prepare what should be.
