About this conversion

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

For everyday use, three or four significant figures are usually enough. Engineering, science and trade documents may need more, and rounding should happen only at the end of a calculation.

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