Conversion Formulas:

• 1 W = 1,000 mW = .001 kW = 1e-6 MW = .001341 hp = 3.41214 BTU/h
• 1 mW = .001 W = 1e-6 kW = 1e-9 MW = 1.341e-6 hp = .003412 BTU/h
• 1 kW = 1,000 W = 1,000,000 mW = .001 MW = 1.34102 hp = 3,412.14 BTU/h
• 1 MW = 1,000,000 W = 1,000,000,000 mW = 1,000 kW = 1,341.02 hp = 3,412,140 BTU/h
• 1 hp = 745.7 W = 745,700 mW = .7457 kW = .0007457 MW = 2,544.43 BTU/h
• 1 BTU/h = .293071 W = 293.071 mW = .000293071 kW = 2.93071e-7 MW = .000393 hp
