About Converting Hectowatts to Megawatts
Hectowatt and Megawatt 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: Hectowatt is 100 watt units, and megawatt is 1000000 watt units.
Formula
megawatts = hectowatts × 0.0001
This factor comes from each unit's defined relationship to the category's base unit: 1 hectowatt equals 100 base units, and 1 megawatt equals 1000000 base units, so dividing one by the other gives the direct hectowatt-to-megawatt factor of 0.0001.
Simple example
1 hW × 0.0001 = 0.0001 MW
1 hectowatt = 0.0001 megawatts.
Real-world example
100 hW × 0.0001 = 0.01 MW
100 hectowatts = 0.01 megawatts.

Reverse conversion: Megawatt to Hectowatt
0.0001 MW × 10000 = 1 hW
0.0001 megawatts = 1 hectowatt.
hectowatts = megawatts × 10000

Frequently asked questions
How many megawatts are in 1 hectowatt?
1 hectowatt equals 0.0001 megawatts, using the exact defined conversion factor rather than an estimate.
How do I convert hectowatt to megawatt?
Multiply the hectowatt value by 0.0001. The converter above does this instantly to whatever precision you set.
How do I convert megawatt back to hectowatt?
Use the reverse factor: 1 megawatt equals 10,000 hectowatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectowatt?
Hectowatt (hW) is a unit of engineering.
What is a megawatt?
Megawatt (MW) is a unit of engineering.
Is the hectowatt to megawatt conversion exact?
Yes. Both hectowatt and megawatt are defined by fixed standards rather than physical artifacts, so the factor of 0.0001 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.
