About Converting Megawatts to Terawatts
Megawatt and Terawatt 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: 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.
