About this conversion
Energy conversions link food labels in kJ and kcal, SP Group bills in kWh and air-conditioner capacity in BTU.
Unit conversion is simply multiplication by a fixed ratio. The ratio between two units of the same quantity never changes, so once you know it you can convert any value in either direction.
Writing the units next to every number while you work is the simplest way to avoid mistakes. If the units do not cancel to leave the one you want, the calculation is set up wrongly.
