About Converting Megawatts to Hectowatts
Megawatt and Hectowatt both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. 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
120 MW × 10000 = 1,200,000 hW
120 megawatts = 1,200,000 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 electricity.
What is a hectowatt?
Hectowatt (hW) is a unit of electricity.
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.
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
