To convert a measurement in megacalories to a measurement in therms, multiply the energy by the following conversion ratio: 0.039657 therms/megacalorie.

Since one megacalorie is equal to 0.039657 therms, you can use this simple formula to convert:

therms = megacalories × 0.039657

The energy in therms is equal to the energy in megacalories multiplied by 0.039657.

For example, here's how to convert 5 megacalories to therms using the formula above.
therms = (5 Mcal × 0.039657) = 0.198283 therms

Megacalories and therms are both units used to measure energy. Keep reading to learn more about each unit of measure.

What Is a Megacalorie?

One megacalorie is equal to 1,000,000 calories, which is the heat needed to raise the temperature of one gram of water from 14.5 to 15.5 degrees Celsius. One megacalorie is equal to 4.184 megajoules.

Megacalories can be abbreviated as Mcal; for example, 1 megacalorie can be written as 1 Mcal.

What Is a Therm?

One therm is a measure of heat energy equal to 100,000 BTU, which are equal to the amount of heat energy required to increase the temperature of one pound of water one degree Fahrenheit. Therms are often used by natural gas companies to measure the heat equivalent of gas used.

The therm is a US customary unit of energy.
