How to Convert Megawatt to BTU per Hour
- 1 MW = 3412141.633 BTU/h
- 1 BTU/h = 2.930710702 × 10⁻⁷ MW
- Example: convert 15 MW to BTU/h: 15 MW = 15 × 3412141.633 BTU/h = 51182124.5 BTU/h
Formula
BTU/h = MW × 3412141.633128
Derivation from SI units:
- 1 MW = 10⁶ W
- 1 BTU/h = 1055.05585262 J ÷ 3600 s = 0.29307107 W
- 1 MW = 1000000 W ÷ 0.2930710701722 W per BTU/h = 3412141.633128 BTU/h
Both units are defined exactly, so the factor is exact. Megawatt definition: megawatt; BTU per Hour definition: BTU per hour.
Worked examples
- A reading of 3 MW converts to 10236424.9 BTU/h.
3 MW × 3412141.633 = 10236424.9 BTU/h - A value of 50 MW is 170607081.7 BTU/h.
50 MW × 3412141.633 = 170607081.7 BTU/h
