About Converting Megawatts to Terawatts
Megawatt and Terawatt both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. 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
100 MW × 0.000001 = 0.0001 TW
100 megawatts = 0.0001 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 engineering.
What is a terawatt?
Terawatt (TW) is a unit of engineering.
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.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
