About Converting Terawatts to Megawatts
Terawatt and Megawatt both describe power output, and the conversion is a routine part of comparing an engine or motor's spec sheet across countries that use different power units. Specifically: Terawatt is 1000000000000 watt units, and megawatt is 1000000 watt units.
Formula
megawatts = terawatts × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 terawatt equals 1e+12 base units, and 1 megawatt equals 1000000 base units, so dividing one by the other gives the direct terawatt-to-megawatt factor of 1000000.
Simple example
1 TW × 1000000 = 1,000,000 MW
1 terawatt = 1,000,000 megawatts.
Real-world example
100 TW × 1000000 = 100,000,000 MW
100 terawatts = 100,000,000 megawatts.
