About this calculator
The Scientific Notation Calculator converts between standard numbers and the a-times-10-to-the-n form scientists use. Enter a regular number to get normalized scientific notation, or enter a coefficient and exponent to expand it back. It also handles the E-notation used by calculators and spreadsheets, plus negative exponents for very small values.
Tip: when adding or subtracting in scientific notation, convert to the same exponent first before touching a digit — it is the step everyone skips, and skipping it guarantees a wrong answer.
