How to Convert British Thermal Units to Kilocalories

To convert a british thermal unit measurement to a kilocalorie measurement, multiply the energy by the conversion ratio. One british thermal unit is equal to 0.252164 kilocalories, so use this simple formula to convert:

kilocalories = british thermal units × 0.252164

The energy in kilocalories is equal to the british thermal units multiplied by 0.252164.

For example, here's how to convert 5 british thermal units to kilocalories using the formula above.
5 BTU = (5 × 0.252164) = 1.260822 kcal

British thermal units and kilocalories are both units used to measure energy. Keep reading to learn more about each unit of measure.

British Thermal Units

British thermal units are a measure of heat energy. Specifically, one british thermal unit is equal to the amount of heat energy required to increase the temperature of one pound of water one degree Fahrenheit. They are often used as a way to rate the energy heat producing appliances such furnaces, and to price heating fuels such as natural gas.

The british thermal unit is a US customary unit of energy. British thermal units can be abbreviated as BTU, for example 1 british thermal unit can be written as 1 BTU.

Kilocalories

One kilocalorie, is equal to the heat needed to raise the temperature of one kilogram of water from 14.5 to 15.5 degrees Celsius.

Kilocalories can be abbreviated as kcal, for example 1 kilocalorie can be written as 1 kcal.

When being used to measure nutrition or metabolic processes, the large calorie is used, which is equal to one kilocalorie.
