About Converting Hectowatts to Megawatts
Hectowatt and Megawatt 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: 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
120 hW × 0.0001 = 0.012 MW
120 hectowatts = 0.012 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 electricity.
What is a megawatt?
Megawatt (MW) is a unit of electricity.
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.
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.
