About Converting Terawatts to Hectowatts
Terawatt 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: Terawatt is 1000000000000 watt units, and hectowatt is 100 watt units.
Formula
hectowatts = terawatts × 10000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 terawatt equals 1e+12 base units, and 1 hectowatt equals 100 base units, so dividing one by the other gives the direct terawatt-to-hectowatt factor of 10000000000.
Simple example
1 TW × 10000000000 = 10,000,000,000 hW
1 terawatt = 10,000,000,000 hectowatts.
Real-world example
120 TW × 10000000000 = 1.2e+12 hW
120 terawatts = 1.2e+12 hectowatts.

Reverse conversion: Hectowatt to Terawatt
1 hW × 1e-10 = 1e-10 TW
1 hectowatt = 1e-10 terawatts.
terawatts = hectowatts × 1e-10

Frequently asked questions
How many hectowatts are in 1 terawatt?
1 terawatt equals 10,000,000,000 hectowatts, using the exact defined conversion factor rather than an estimate.
How do I convert terawatt to hectowatt?
Multiply the terawatt value by 10000000000. The converter above does this instantly to whatever precision you set.
How do I convert hectowatt back to terawatt?
Use the reverse factor: 1 hectowatt equals 1e-10 terawatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a terawatt?
Terawatt (TW) is a unit of electricity.
What is a hectowatt?
Hectowatt (hW) is a unit of electricity.
Is the terawatt to hectowatt conversion exact?
Yes. Both terawatt and hectowatt are defined by fixed standards rather than physical artifacts, so the factor of 10000000000 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.
