How to use this calculator

  1. Enter part in number.
  2. Enter whole in number.
  3. Select Calculate and keep the output unit with the answer.

Before you use the answer

Choose the reference quantity before interpreting the number. A ratio, a percentage and a percentage-point difference may use the same observations while answering different questions. For recorded data, keep the original values beside the summary so an unexpected result can be traced back to its inputs.

Use matching units for the part and whole. The denominator must be positive.

Why might a result be approximate?

Measurement uncertainty, ideal-model assumptions and floating-point rounding can all matter. Displaying more digits does not improve the original measurement.
