British thermal units to Kilocalories Converter

British thermal units

The British thermal unit (BTU) is a unit of energy approximately equal to 1,055.06 joules, defined as the energy required to raise the temperature of one pound of water by one degree Fahrenheit. It remains the standard unit for heating and cooling capacity in HVAC systems in the United States: air conditioners and furnaces are rated in BTU/hour. A typical residential air conditioner is rated at 5,000–24,000 BTU/h. One BTU equals approximately 0.000293 kWh.

Kilocalories

The kilocalorie (kcal), commonly called a "Calorie" (capital C) in nutritional contexts, is a unit of energy equal to exactly 4,184 joules. It represents the energy needed to raise 1 kg of water by 1 °C. In nutrition, all food energy values are expressed in kcal per gram: carbohydrates and protein provide 4 kcal/g; fat provides 9 kcal/g; alcohol provides 7 kcal/g. An average adult requires approximately 2,000–2,500 kcal per day to maintain body weight.
