About this calculator

Use this for electricity bills, food energy, and heating figures that refuse to share a unit. Type the amount, pick the unit on the bill or label, then pick the unit you want.

Everything is converted through the joule. Calories here are thermochemical (1 cal = 4.184 J). A therm is 100 000 IT BTU (the US therm). Natural-gas CCF is not energy until you pick a heat content — use therms if you already have them.

Value: The energy amount you have.

From: The unit on the bill, label, or spec.

To: The unit you want to compare it in.

Result: The same energy in the To unit.
