About Converting BTU per hour to Quettawatts
BTU per hour and Quettawatt 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: Power rate using BTU per hour, and quettawatt is 1e+30 watt units.
Formula
quettawatts = btu per hour × 2.930711e-31
This factor comes from each unit's defined relationship to the category's base unit: 1 btu per hour equals 0.293071070172 base units, and 1 quettawatt equals 1e+30 base units, so dividing one by the other gives the direct btu per hour-to-quettawatt factor of 2.930711e-31.
Simple example
1 BTU/h × 2.930711e-31 = 2.930711e-31 QW
1 btu per hour = 2.930711e-31 quettawatts.
Real-world example
100 BTU/h × 2.930711e-31 = 2.930711e-29 QW
100 btu per hour = 2.930711e-29 quettawatts.
