About Converting Hectowatts to Decawatts
Hectowatt and Decawatt 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 decawatt is 10 watt units.
Formula
decawatts = hectowatts × 10
This factor comes from each unit's defined relationship to the category's base unit: 1 hectowatt equals 100 base units, and 1 decawatt equals 10 base units, so dividing one by the other gives the direct hectowatt-to-decawatt factor of 10.
Simple example
1 hW × 10 = 10 daW
1 hectowatt = 10 decawatts.
Real-world example
120 hW × 10 = 1,200 daW
120 hectowatts = 1,200 decawatts.

Reverse conversion: Decawatt to Hectowatt
10 daW × 0.1 = 1 hW
10 decawatts = 1 hectowatt.
hectowatts = decawatts × 0.1

Frequently asked questions
How many decawatts are in 1 hectowatt?
1 hectowatt equals 10 decawatts, using the exact defined conversion factor rather than an estimate.
How do I convert hectowatt to decawatt?
Multiply the hectowatt value by 10. The converter above does this instantly to whatever precision you set.
How do I convert decawatt back to hectowatt?
Use the reverse factor: 1 decawatt equals 0.1 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 decawatt?
Decawatt (daW) is a unit of electricity.
Is the hectowatt to decawatt conversion exact?
Yes. Both hectowatt and decawatt are defined by fixed standards rather than physical artifacts, so the factor of 10 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.
