About Converting Megawatts to Hectowatts
Megawatt and Hectowatt both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: Megawatt is 1000000 watt units, and hectowatt is 100 watt units.
Formula
hectowatts = megawatts × 10000
This factor comes from each unit's defined relationship to the category's base unit: 1 megawatt equals 1000000 base units, and 1 hectowatt equals 100 base units, so dividing one by the other gives the direct megawatt-to-hectowatt factor of 10000.
Simple example
1 MW × 10000 = 10,000 hW
1 megawatt = 10,000 hectowatts.
Real-world example
100 MW × 10000 = 1,000,000 hW
100 megawatts = 1,000,000 hectowatts.

Reverse conversion: Hectowatt to Megawatt
1 hW × 0.0001 = 0.0001 MW
1 hectowatt = 0.0001 megawatts.
megawatts = hectowatts × 0.0001

Frequently asked questions
How many hectowatts are in 1 megawatt?
1 megawatt equals 10,000 hectowatts, using the exact defined conversion factor rather than an estimate.
How do I convert megawatt to hectowatt?
Multiply the megawatt value by 10000. The converter above does this instantly to whatever precision you set.
How do I convert hectowatt back to megawatt?
Use the reverse factor: 1 hectowatt equals 0.0001 megawatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a megawatt?
Megawatt (MW) is a unit of engineering.
What is a hectowatt?
Hectowatt (hW) is a unit of engineering.
Is the megawatt to hectowatt conversion exact?
Yes. Both megawatt and hectowatt are defined by fixed standards rather than physical artifacts, so the factor of 10000 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
