Scientific Notation Calculator
Convert an ordinary number into scientific notation, a number between 1 and 10 times a power of ten.
Formula
Scientific notation writes a number as a mantissa between 1 and 10, multiplied by 10 raised to an exponent.
How it works
Enter any non-zero number. The calculator shifts the decimal point until one digit sits before it, and counts the shifts as the exponent.
