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 nutritional calorie is the amount of energy needed to warm 1 kilogram of water by 1° C. It is equal to 4,184 J
