How to Convert a Number to Scientific Notation

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

To enter a number in scientific notation, use a caret (^) to indicate powers of 10. Examples: 3.45 x 10^5 or 3.45e5.

Steps to Convert a Number to Scientific Notation

  1. Move the decimal point until there is only one non-zero digit to the left.
  2. Count how many places the decimal point moved. This becomes the exponent.
  3. If the decimal moves to the left, the exponent is positive; if it moves to the right, it is negative.
  4. Write the number as a × 10^b, where "a" is the decimal number and "b" is the exponent.

Examples:

Convert 357,096 to scientific notation:

  • Move decimal 5 places left: 3.57096
  • a = 3.57096, b = 5
  • Result: 3.57096 x 10^5

Convert 0.005600 to scientific notation:

  • Move decimal 3 places right: 5.600
  • a = 5.600, b = -3
  • Result: 5.600 x 10^-3
