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
A kiloton of TNT is the amount of energy released in the detonation of 1,000 metric tons of TNT. It equates to 4.184 terajoules
