      Relation Between British Thermal Unit (BTU) and Calorie (cal)

      Let me explain to you about the relation between British Thermal Unit BTU and Calorie (cal) first before moving to the conversion process. Because it’s essential to grasp what these units represent.

      What is British Thermal Unit (BTU)?

      A British Thermal Unit is the amount of heat energy required to raise the temperature of one pound of liquid water by one degree Fahrenheit. British Thermal Unit (BTU) is a unit of energy measurement which is commonly used in Heating, Energy. BTUs are commonly used in the United States and other countries that use the imperial system to measure the energy content of fuels, the efficiency of heating and cooling systems, and the energy consumption of appliances..

      What is Calorie (cal)?

      British Thermal Unit (BTU) is another unit of energy measurement that is used in Nutrition, Energy. A calorie is the amount of heat energy required to raise the temperature of one gram of pure water by one degree Celsius.. BTUs are commonly used in the United States and other countries that use the imperial system to measure the energy content of fuels, the efficiency of heating and cooling systems, and the energy consumption of appliances..

      How to Convert Calorie (cal)?

      The conversion between British Thermal Unit (BTU) and Calorie (cal) follows a simple formula:

      British Thermal Unit = British Thermal Unit × 252

      Where, 252 is the value that allows you to convert between British Thermal Unit (BTU) and Calorie (cal).

      So,

      1 Calorie = 252 British Thermal Unit

      And, 1 British Thermal Unit = 1/252 Calorie

      Examples of Converting British Thermal Unit (BTU) to Calorie (cal)

      To convert any value from British Thermal Unit (BTU) to Calorie (cal), simply multiply the amount of British Thermal Unit (BTU) by the conversion factor:

      1 Calorie = 252 British Thermal Unit

      For example, if you want to convert 5 British Thermal Unit into Calorie and the conversion factor is 252, then:

      5 British Thermal Unit = 5 x 252 Calorie
