How to Convert Calories to Quads

To convert a calorie measurement to a quad measurement, divide the energy by the conversion ratio.

Since one quad is equal to 2.5216E+17 calories, you can use this simple formula to convert:

quads = calories ÷ 2.5216E+17

The energy in quads is equal to the calories divided by 2.5216E+17.

For example, here's how to convert 5.0E+17 calories to quads using the formula above.
5.0E+17 cal = (5.0E+17 ÷ 2.5216E+17) = 1.982833 quads

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


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.


One therm is a measure of heat energy equal to one quadrillion (1,000,000,000,000,000) BTU, which are equal to the amount of heat energy required to increase the temperature of one pound of water one degree Fahrenheit. Quads are usually used when talking about energy resources and consumption on a national or international scale.

The quad is a US customary unit of energy.
