How to use
Choose conversion or arithmetic, then enter a standard number without commas, an e-notation value, or a value written with × 10^. Arithmetic modes use both inputs. Calculate to see the normalized coefficient and exponent.
Scientific notation writes a nonzero number as a × 10ⁿ, with 1 ≤ |a| < 10. Multiply coefficients and add exponents for multiplication; divide coefficients and subtract exponents for division.
Worked examples
Example 1
123,000,000 = 1.23 × 10⁸. Enter 123000000 without grouping commas.
Inputs support 1.23e8 or 1.23 × 10^8. Zero is represented as 0 × 10^0.
Uses approximately 15–16 significant digits. Values outside finite JavaScript limits are rejected; very large or small standard forms remain in scientific notation.
