About Units

Btu: British Thermal Units (BTU) are a measure of heat energy. One BTU is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. This unit is commonly used in the power, steam generation, and heating, ventilation, and air conditioning (HVAC) industries.

Kilowatt hours: Kilowatt-hours (kWh) are equal to 1,000 watt-hours. This unit is commonly used for measuring electrical energy consumption, especially in household and industrial contexts. Electric utility companies use kilowatt-hours to measure and bill for energy consumption.
