One BTU is the energy required to heat 1 avoirdupois pound of liquid water by 1 degree Fahrenheit, at a pressure of one atmosphere. The Btu (mean) uses a result averaged over water temperatures 0 to 100 °C (32.0 to 212.0 °F) which is approx. 1055.87 J
One calorie (Kilogram,mean) is the amount of energy needed to heat one kg of air-free water from 0 to 100°C at standard atmospheric pressure, divided by 100.It's value is 4,190.02 J
