We’ve already discussed the difference between kW and kWh in a previous post: kW being kiloWatt – a measure of power; kWh being kiloWatt-hour – a measure of energy.
British Thermal Units (BTU)
A BTU can be approximated as the heat produced by burning a single wooden kitchen match or as the amount of energy it takes to lift a one-pound weight 778 feet (237 m).
One BTU is approximately:
- 1.054 to 1.060 kJ (kilojoules)
- 0.293071 W·h (watt hours)
- 0.000393081 hp
One Watt is approximately:
- 3.41214 BTU/h
Now the question is how to convert between British Thermal Units (BTU) and kW.
Conversion Formulas for BTU/h to kWh
Using this information, we can understand the following formulas:
Watt-hour = BTU/hour * 0.29307107 BTU/hour = Watt-hour/0.2930717
Hope this helps!
