Step-by-step example — Convert 5000 BTU to J:
A BTU (British Thermal Unit) is an imperial energy unit, used mainly for rating heating and cooling equipment.
A Joule (J) is the SI unit of energy, used as the scientific standard for measuring work and heat.
The formula is: Joule = BTU x 1055.06. Multiply any BTU value by 1055.06 to get the equivalent in Joule.
1 BTU = 1055.06 J.
1 J = 0.000947813394498891 BTU.
BTU is bigger than Joule. 1 BTU = 1055.06 J.
12000 BTU = 12,660,720 J.
5000 J = 4.739066972 BTU.
Cooling capacity is rated in BTU per hour because it directly measures how much heat a unit can remove from a room in a given time — a higher rating means it can cool a larger space.
