About Converting Terawatts to Decawatts
Terawatt and Decawatt 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 decawatt is 10 watt units.
Formula
decawatts = terawatts × 100000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 terawatt equals 1e+12 base units, and 1 decawatt equals 10 base units, so dividing one by the other gives the direct terawatt-to-decawatt factor of 100000000000.
Simple example
1 TW × 100000000000 = 100,000,000,000 daW
1 terawatt = 100,000,000,000 decawatts.
Real-world example
100 TW × 100000000000 = 1e+13 daW
100 terawatts = 1e+13 decawatts.
