BTUs per hour to Milliwatts Converter
1 BTU per hour (BTU/h) equals 293.071070172 milliwatts (mW).
Quick answer
- 1 BTU per hour = 293.0710702 milliwatts
- 1 milliwatt = 0.003412141633 BTUs per hour
- Formula: mW = BTU/h × 293.071070172
1 BTU per hour = 293.0710702 milliwatts
How to convert BTUs per hour to milliwatts
mW = BTU/h × 293.071070172
To convert BTUs per hour to milliwatts, multiply the number of BTUs per hour by 293.071070172.
Example: 10 BTU/h to mW
- Start with the value in BTUs per hour: 10 BTU/h.
- Multiply by 293.071070172: 10 × 293.071070172 = 2,930.710702.
- Result: 10 BTUs per hour = 2,930.710702 milliwatts.
Going the other way, 1 milliwatt = 0.003412141633 BTUs per hour, so to convert milliwatts back to BTUs per hour you divide by the same number. See milliwatts to BTUs per hour.
