How to use the Scientific Notation Converter

  1. Type a number — 123000, 0.00042, 6.02e23 or 4.5 × 10^-3.

What does this tool do?

Scientific notation writes a number as a value between 1 and 10 multiplied by a power of ten: 45,600 becomes 4.56 × 10⁴. It keeps very large and very small numbers readable.

Engineering notation uses powers of ten that are multiples of three, matching prefixes like kilo, mega and milli.

Why use it?

  • Three notations at once.
  • Significant figures control.
  • Accepts many input formats.
