To convert a measurement in calories to a measurement in british thermal units, multiply the energy by the following conversion ratio: 0.003966 british thermal units/calorie.
Since one calorie is equal to 0.003966 british thermal units, you can use this simple formula to convert:
british thermal units = calories × 0.003966
The energy in british thermal units is equal to the energy in calories multiplied by 0.003966.
Calories and british thermal units 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 British Thermal Unit?
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.
