About Converting Megawatts to Terawatts
Megawatt and Terawatt 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 terawatt is 1000000000000 watt units.
Formula
terawatts = megawatts × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 megawatt equals 1000000 base units, and 1 terawatt equals 1e+12 base units, so dividing one by the other gives the direct megawatt-to-terawatt factor of 0.000001.
Simple example
1 MW × 0.000001 = 0.000001 TW
1 megawatt = 0.000001 terawatts.
Real-world example
120 MW × 0.000001 = 0.00012 TW
120 megawatts = 0.00012 terawatts.

Reverse conversion: Terawatt to Megawatt
0.000001 TW × 1000000 = 1 MW
0.000001 terawatts = 1 megawatt.
megawatts = terawatts × 1000000

Frequently asked questions
How many terawatts are in 1 megawatt?
1 megawatt equals 0.000001 terawatts, using the exact defined conversion factor rather than an estimate.
How do I convert megawatt to terawatt?
Multiply the megawatt value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert terawatt back to megawatt?
Use the reverse factor: 1 terawatt equals 1,000,000 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 terawatt?
Terawatt (TW) is a unit of electricity.
Is the megawatt to terawatt conversion exact?
Yes. Both megawatt and terawatt are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 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.
