How to convert mechanical horsepower to Btu IT per hour
Mechanical horsepower is 550 foot-pounds-force per second. Metric horsepower uses 75 kilogram-force meters per second and has a different value.
Use x for the value in hp, b for the intermediate value in W, and y for the result in Btu IT/h.
Btu IT/h = hp × 745.6998715822702 ÷ 0.2930710701722222
Worked examples
10 hp ≈ 25444.3357764 Btu IT/h
Step 1: (10 × 745.699871582) ≈ 7456.99871582 W.
Step 2: 7456.99871582 ÷ 0.293071070172 ≈ 25444.3357764 Btu IT/h.20 hp ≈ 50888.6715529 Btu IT/h
Step 1: (20 × 745.699871582) ≈ 14913.9974316 W.
Step 2: 14913.9974316 ÷ 0.293071070172 ≈ 50888.6715529 Btu IT/h.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
