1 Horsepower (mech) = 0.0007 Megawatt
Key Formulas
Kilowatt → Horsepower (mech)
hp = kW × 1.34102Horsepower (mech) → Kilowatt
kW = hp × 0.7457Watt → Kilowatt
kW = W × 0.001Kilowatt → Watt
W = kW × 1000Formula
MW = hp × 0.000745700Marine engineers, locomotive designers, and large industrial system operators sometimes need to express engine ratings — traditionally quoted in horsepower — in the megawatts used for grid-connected power and international engineering standards. A cruise ship's propulsion plant rated 100,000 hp = 74.6 MW. This conversion also appears when comparing large gas turbine generator sets whose prime mover may be rated in hp while the electrical output is quoted in MW.
