Put simply, one British Thermal Unit [Btu] is the amount of heat required to raise the temperature of
1 pound [ lb.] of water 1 degree Fahrenheit.
The Fifth International Conference on the Properties of Steam (London, July 1956) defined the International Table calorie as 4.1868 joule.
Therefore the exact conversion factor for the International Table British thermal unit (Btu) is 1.05505585262 kJ.
The thermochemical Btu is based on the thermochemical calorie which equals 4.184 joule exactly.
Note that reference is often made to the calorie when in actual fact the kilocalorie (also called Calorie, large calorie or kilogram calorie) is meant. (1 kilocalorie = 1000 calories) |

How to convert Volt Ampere to Btu Per Hour (VA to BTU/h)? 1 VA = 3.28 BTU/h. 1 x 3.28 BTU/h = 3.28 Btu Per Hour. Always check the results; rounding errors may occur. Definition: In relation to the base unit of power = (watts), 1 Volt Ampere (VA) is equal to 1 watts, while 1 Btu Per Hour (BTU/h) = 0. 1 BTU/h = 0.7222 VA. 1 x 0.7222 VA = 0.7222 Volt Ampere. Always check the results; rounding errors may occur. Convert tons to amps, you must first convert tons to BTUs per hour, after which you can convert this value to watts, then use the formula amps = watts / volts to solve for amps. Convert tons to BTUs per hour by multiplying it by 12,000. Given an air conditioner with 2 tons of. Nominal voltage of 120V, the maximum heater rating is 120 Volts x 12 Amps max which means 1440 Volt-amps max assuming it is a standard resistance heater. If the circuit breaker (CB) is a 15 Amp 2-pole CB and the nominal voltage between the two poles is 240V; the maximum heater rating would be 80% x 15A x 240V = 2880 Volt-Amps max.
