About this conversion

Energy conversions link food labels in kJ and kcal, SP Group bills in kWh and air-conditioner capacity in BTU.

Many conversion factors are exact by definition. The inch has been defined as exactly 2.54 centimetres since 1959, and the pound as exactly 0.45359237 kilograms, so conversions involving them can be as precise as you need.

A conversion table is handy for common values, but a calculator is faster and avoids interpolation errors for anything in between.
