The JOULE (J) is a commonly used unit of energy. The BTU is also an unit of energy. Another typical unit for energy is KWhr (KiloWattHour). 1kJ (KiloJoule) = 0.9485 BTU=0.0002778 kWhr
The Watt (W) is a unit for power i.e. the energy used (or supplied) per unit time. 1 J/s (Joule per second) = 1 W (Watt)
PowerUnits Conversion 1kW (KiloWatt) = 3414 BTU/hr
How much energy and what kind of power will be suitable for your heating application? The calculators below may be used to calculate the energy required for common processes. Then by choosing a time over which the energy will be used one can calculate the best power required from the heater.
