About Converting Decawatts to Terawatts
Decawatt 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: Decawatt is 10 watt units, and terawatt is 1000000000000 watt units.
Formula
terawatts = decawatts × 1e-11
This factor comes from each unit's defined relationship to the category's base unit: 1 decawatt equals 10 base units, and 1 terawatt equals 1e+12 base units, so dividing one by the other gives the direct decawatt-to-terawatt factor of 1e-11.
Simple example
1 daW × 1e-11 = 1e-11 TW
1 decawatt = 1e-11 terawatts.
Real-world example
100 daW × 1e-11 = 1e-9 TW
100 decawatts = 1e-9 terawatts.
