How many joules are in a British thermal unit (IT)?
One IT British thermal unit is approximately 1,055.056 joules.
Detailed answer
This tool uses the international table BTU (IT): 1 BTU ≈ 1,055.05585262 J. HVAC equipment and US datasheets often quote BTU or BTU/h.
Relationship context
BTU connects imperial heating/cooling ratings to SI joules for efficiency comparisons.
