Horsepower x 2,544 = Btu
Btu is a unit of heat.Horse power is the measurement of power.Now,in order to correlate BTU and HP,We can say BTU*TIME(Hr)*3.931e-4=Horsepower. Hence 48000 BTU Hr is 18.8 Horsepower
1hp = 2544 Btu
12,000 Btu is 4.7hp
This is a power unit conversion from British thermal units per hour (Btu/hr.) to its equivalent in horsepower (hp). There are 2544.43 btu/hr. in one horsepower. Conversely, there are 0.000393 hp in one Btu/hr.
400hp is 1,017,773 Btu
Horsepower is a measure of power, so it should be measured in watts.
To convert Cubic Feet to Btu's, multiply by 1,000 1 CF = 1,000 Btu's
33,475 btu's in a boiler horse power
1 BTU = 1,055 Joules
Calories x 0.003968 = BTU
LRA is not any known unit of measure. You can convert horsepower to BTU per hour, calories per second, ergs per second, watts, Kilowatts, MW, GW, etc.
10000Btu is 3.93hp
