About Converting BTU per hour to Nanowatts
BTU per hour and Nanowatt 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 nanowatt is 1e-9 watt units.
Formula
nanowatts = btu per hour × 293071070.172
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 nanowatt equals 1e-9 base units, so dividing one by the other gives the direct btu per hour-to-nanowatt factor of 293071070.172.
Simple example
1 BTU/h × 293071070.2 = 293,071,070.2 nW
1 btu per hour = 293,071,070.2 nanowatts.
Real-world example
100 BTU/h × 293071070.2 = 29,307,107,020 nW
100 btu per hour = 29,307,107,020 nanowatts.
Conversion table
| BTU per hour (BTU/h) | Nanowatt (nW) |
|---|---|
| 1 BTU/h | 293,071,070.2 nW |
| 10 BTU/h | 2,930,710,702 nW |
| 100 BTU/h | 29,307,107,020 nW |
| 500 BTU/h | 146,535,535,100 nW |
| 1,000 BTU/h | 293,071,070,200 nW |
| 5,000 BTU/h | 1.465355e+12 nW |
Reverse conversion: Nanowatt to BTU per hour
1 nW × 3.412142e-9 = 3.412142e-9 BTU/h
1 nanowatt = 3.412142e-9 btu per hour.
btu per hour = nanowatts × 3.412142e-9
