## How to Convert Calories to Therms

To convert a measurement in calories to a measurement in therms, multiply the energy by the following conversion ratio: 3.9657E-8 therms/calorie.

Since one calorie is equal to 3.9657E-8 therms, you can use this simple formula to convert:

therms = calories × 3.9657E-8

The energy in therms is equal to the energy in calories multiplied by 3.9657E-8.

**For example,**here's how to convert 50,000,000 calories to therms using the formula above.

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

## What Is a Calorie?

One calorie is equal to the heat needed to raise the temperature of one gram of water from 14.5 to 15.5 degrees Celsius.

When measuring the energy content in foods, the large calorie, or kilocalorie is used, but it's often still just called a "calorie." When both the calorie and large calorie are used in the same context it is common to refer to the calorie as a "small calorie."

Calories can be abbreviated as *cal*; for example, 1 calorie can be written as 1 cal.

## 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.
