How do you calculate horsepower in air condition compressor?

To calculate the horsepower (HP) of an air conditioning compressor, you can use the formula: HP = (BTU/hr) / (2,545), where BTU/hr is the cooling capacity of the compressor. Alternatively, if you have the compressor's power consumption in watts, you can convert it to horsepower using the formula: HP = (watts) / (746). Make sure to account for efficiency by multiplying by the efficiency factor if necessary.
