Frequently Asked Questions
What is scientific notation?▾
A way to express very large or small numbers as a × 10^n where 1 ≤ a < 10. E.g. 0.000045 = 4.5 × 10^-5, and 6,020,000 = 6.02 × 10^6.
How do you multiply in scientific notation?▾
Multiply the coefficients and add the exponents: (a × 10^m) × (b × 10^n) = (a×b) × 10^(m+n). The tool handles any normalisation automatically.
How do I enter scientific notation values?▾
Use standard decimal notation or scientific e-notation: 6.02e23 means 6.02 × 10^23. Both formats work.
