Scientific Notation Calculator
Convert numbers to and from scientific notation and calculate sums, differences, products and quotients with significant figures.
Convert and calculate numbers in scientific notation
Use this calculator to convert ordinary numbers to coefficient-times-power-of-ten form or calculate directly with e notation.
The result identifies the coefficient, base-10 exponent, standard form and the significant figures in the first input.

Related formulas
Scientific notation: a × 10^n, where 1 ≤ |a| < 10.Multiplication: (a × 10^m)(b × 10^n) = ab × 10^(m+n).Division: (a × 10^m)/(b × 10^n) = (a/b) × 10^(m−n).
FAQ
What does 1.23e6 mean?
It means 1.23 × 10^6, which is 1,230,000.
Can I calculate with scientific notation?
Yes. Enter e notation in either number field and choose add, subtract, multiply or divide.
What are significant figures?
They are the meaningful digits in a measured number, beginning with the first non-zero digit.
Does this use Euler's number e?
No. On this page e is the standard input shorthand for a power of ten.
