How to convert btu to joules
BTU (British Thermal Unit) and joules measure thermal energy. One BTU is the energy to heat one pound of water by 1°F, equal to 1,055.06 joules. BTU appears in HVAC ratings, gas appliance specs, and heating fuel comparisons.
Multiply BTU by 1,055.06 to get joules. Formula: J = BTU × 1,055.06. 1 BTU = 1,055 J. A 10,000 BTU/hr air conditioner removes 10,550,600 J per hour. A 100,000 BTU furnace = 105,506,000 J output.
HVAC shopping (BTU cooling capacity), natural gas billing (therms = 100,000 BTU), and energy efficiency comparisons use this conversion.
Also: 1 kWh = 3,412 BTU. 1 therm = 100,000 BTU = 105.5 MJ.
