To convert a measurement in therms to a measurement in megacalories, multiply the energy by the following conversion ratio: 25.21644 megacalories/therm.

Since one therm is equal to 25.21644 megacalories, you can use this simple formula to convert:

megacalories = therms × 25.21644

The energy in megacalories is equal to the energy in therms multiplied by 25.21644.

For example, here's how to convert 5 therms to megacalories using the formula above.
megacalories = (5 therms × 25.21644) = 126.0822 Mcal

How Many Megacalories Are in a Therm?
