Common Questions
What is the Energy converter used for?
Energy is the capacity to do work. Joules underpin SI, watt-hours and kilowatt-hours describe electricity consumption, and calories or British thermal units express heat content in food and HVAC. Convert to compare fuel use, utility bills, or equipment output.
What is the difference between a Joule and a Watt-hour?
A Joule (J) is the SI base unit of energy representing one watt of power expended for one second. A Watt-hour (Wh) represents one watt expended continuously for an entire hour (3,600 seconds). Therefore, 1 Wh equals exactly 3,600 Joules.
How do you convert BTUs to kWh for HVAC equipment?
One British Thermal Unit per hour (BTU/hr) represents the heat energy required to raise the temperature of one pound of water by 1°F. To convert BTUs of heat energy directly to kilowatt-hours (kWh), multiply the BTU value by 0.000293071.
