Why Convert Horsepower to Megawatts?

Converting between horsepower (hp) and megawatts (MW) is one of the most common power conversions. Whether for engineering, cooking, travel, or science, knowing how to quickly convert hp to MW saves time and prevents errors.

Power conversions (hp to MW) are essential for automotive enthusiasts, electrical engineers, and athletes. Car buyers frequently convert horsepower to kilowatts to compare engine performance across international brands. In electrical engineering, sizing generators and motors requires consistent power units to prevent overloads and ensure compatibility. Cyclists and rowers use power meters to track output in watts, converting these figures to estimate calorie burn or compare efforts. Misinterpreting power ratings can result in buying underpowered equipment or damaging electrical systems, highlighting the need for accurate conversion tools.

How to Convert Horsepower to Megawatts

To convert horsepower to megawatts, use the following formula:

MW = hp × 0.0007456998716

Example: 1 hp = 0.0007456998716 MW

For example, 5 hp = 0.003728499358 MW, 10 hp = 0.007456998716 MW, and 100 hp = 0.07456998716 MW. For larger values, 1000 hp = 0.7456998716 MW. Conversely, 1 MW = 1341.02209 hp. Our calculator above performs this conversion instantly with full precision — no rounding errors.

Common Mistakes to Avoid

kW vs kWh: kW is power (rate), kWh is energy (total used).
HP variations: Mechanical HP (~745.7W) vs Metric HP (~735.5W).
Apparent Power: Watts vs Volt-Amps (VA) differ due to power factor.

Pro Tips

LED bulbs: A 10W LED replaces a 60W incandescent (saves energy).
Appliance labels: Check the back label for Wattage to avoid overloading strips.
Solar panels: Ratings are 'Peak Watts' (ideal conditions), expect less in reality.

What is a Horsepower?

Horsepower (hp) is a unit of power. Mechanical horsepower is about 745.7 watts, while metric horsepower is roughly 735.5 watts.

Horsepower is the traditional unit for measuring the power of car engines and electric motors, particularly in the automotive industry.

What is a Megawatt?

A unit of power equal to 1,000,000 Watts.

Power plant output.
