Exponential Notation Calculator

Let's start with what exponential notation is. Exponential notation, or E notation, is one of many names referring to scientific notation.

It is a method to convert very small or very large numbers into a quickly readable format that doesn't keep out too much information about the number.

The only difference between regular scientific notation and exponential notation is the swap of the factor by or, less frequently, , both followed by the exponent .

Our exponential notation calculator automatically outputs any number you write converted to e notation. Read the following section to learn how to do it by yourself!

To convert a number to exponential notation:

1. Write down the number, e.g., 0.00023453.
2. Move the decimal point to the right of the first non-zero digit.
3. Compare to the original number:
   • If the decimal moved left, the exponent is positive; else
   • The exponent is negative.
4. Count the number of places moved. This is the exponent.
5. Write the first three non-zero digits (round the last) followed by e and the exponent. Example: 2.35e-4.

Give it a try! Follow the steps and then compare the result with our exponential notation calculator.
