How to convert Joules to British Thermal Units
Multiply the joules value by 0.000947813: 1 J = 0.000947813 BTU. Going the other way, 1 BTU = 1,055.06 J, so divide by 0.000947813 or use the British Thermal Units to Joules converter.
About these units
Joules (J)
The joule is the SI unit of energy: the work done by a force of one newton over one meter. Lifting a small apple one meter takes about one joule.
British Thermal Units (BTU)
A British thermal unit is the energy needed to raise one pound of water by one degree Fahrenheit, about 1,055 joules. Heating and air-conditioning capacities are rated in BTU per hour.
