gigawatt to mechanical horsepower
Convert gigawatt (GW) to mechanical horsepower (hp). Use an editable power converter, conversion formula, and reference table.
1 GW = 1,341,022.09 hp
Conversion formula
One gigawatt equals 1,341,022.09 mechanical horsepower. Multiply your value in gigawatt by this factor to get mechanical horsepower. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 gigawatt:5 × 1,341,022.09 = 6,705,110.448 hp

About these measurements
Power is the rate of energy transfer.
The base reference used here is the watt. One gigawatt is 1,000,000,000 base units; one mechanical horsepower is 745.6998716 base units.
Important distinctions
Mechanical horsepower and metric horsepower are distinct units.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
