What is a metric horsepower?
Exactly 75 kilogram-force metres a second, which is 1.4% less than mechanical horsepower. A German car quoted at 150 PS is 148 hp, and the difference is the definition rather than the engine.
What is a BTU per hour?
The rate US heating and air conditioning is sold in. A 12,000 BTU/h unit is one "ton" of cooling and about 3.5 kilowatts of heat moved.
How many BTU per hour are in a metric horsepower?
One metric horsepower is 2509.6259 BTU per hour. Going the other way, one BTU per hour is 3.9847 × 10^-4 metric horsepower. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
