Convert a number to and from scientific notation, e notation, engineering notation, standard form, and real numbers. Enter a number or a decimal number or scientific notation and the calculator converts to scientific notation, e notation, engineering notation, and standard form formats.

To enter a number in scientific notation use a carat ^ to indicate the powers of 10. You can also enter numbers in e notation. Examples: 3.45 x 10^5 or 3.45e5.

## How to Convert a Number to Scientific Notation

The proper format for scientific notation is ax10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1≤|a| Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a. Count how many places you moved the decimal point. This number is b. If you moved the decimal to the left b is positive. If you moved the decimal to the right b is negative. If you did not need to move the decimal b = 0. Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b." Remove trailing 0"s only if they were originally to the left of the decimal point.

### Example: Convert 357,096 to Scientific Notation

Move the decimal 5 places to the left to get 3.57096 a = 3.57096 We moved the decimal to the left so b is positive b = 5 The number 357,096 converted to scientific notation is 3.57096 x 10^5

### Example: Convert 0.005600 to Scientific Notation

Move the decimal 3 places to the right and remove leading zeros to get 5.600 a = 5.600 We moved the decimal to the right so b is negative b = -3 The number 0.005600 converted to scientific notation is 5.600 x 10^-3

E notation is basically the same as scientific notation except that the letter e is substituted for "x 10^".
