Order of Magnitude Calculator

Your details

Single mode finds the order of magnitude of one number. Compare mode shows the scale difference between two quantities.
Any positive or negative number, including decimals. For example: 1370, 0.082, or 5972000000000000000000000.

Order of magnitude: 3 (the number is at the 10^3 scale).

  • In scientific notation: 1.37 x 10^3.
  • At this scale: roughly the scale of a city block or a small room in metres.
  • Orders of magnitude let scientists and engineers compare extremely different scales without getting lost in zeros.
