One horsepower can generate heat energy equal to:
A
2455 BTU/hr
B
2545 BTU/hr
C
2445 BTU/hr
D
NOTA
Explanation: 

Detailed explanation-1: -The electrical equivalent of one horsepower is 746 watts in the International System of Units (SI), and the heat equivalent is 2, 545 BTU (British Thermal Units) per hour. Another unit of power is the metric horsepower, which equals 4, 500 kilogram-metres per minute (32, 549 foot-pounds per minute), or 0.9863 horsepower.

Detailed explanation-2: -1 HP = 9, 000 BTU/hr This means that 1 HVAC horsepower is equal to 9, 000 BTU per hour. Example: 1 HP air conditioner is the same as a 9, 000 BTU air conditioner.

Detailed explanation-3: -Basically, 1 BTU/hr is equal to 1/9, 000 HP or 0.000111 HP.

Detailed explanation-4: -To calculate the HP from BTU, divide BTU by the time in hours, then multiply by 2545.

Detailed explanation-5: -In other words, the BTU defines how much HP is required to cool a room effectively. Usually, a 1HP air conditioner can remove 9, 000 BTU/hour of heat. With better technology, some air conditioners can remove up to 10, 000 BTU/hour of heat with the same capacity (for calculation purpose, 1 HP ≡ 9, 500 BTU/hour).
