Btu (I.T., pre-1956) to Kilojoules conversion formula
Kilojoules = Btu (I.T., pre-1956) * 1.0550404
Btu (I.T., pre-1956) to Kilojoules calculation
Kilojoules = Btu (I.T., pre-1956) * 1.0550404
Kilojoules = 1 * 1.0550404027722
Kilojoules = 1.05504
Btu (I.T., pre-1956)
The Btu (I.T., pre-1956) refers to the International Table Btu, a specific definition used before 1956. It represents the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit at a constant pressure of one atmosphere.
Kilojoules
A kilojoule (kJ) is equivalent to one thousand joules (J). It is the energy required when a force of one thousand newtons is applied over a distance of one meter, or one newton applied over a kilometer. In reality, a joule is roughly the energy required to lift a small apple one meter against Earth's gravity.
