Kilowatt (kW)
The kilowatt (symbol: kW) is a unit of power in the International System of Units (SI) equal to 1,000 watts:
1 kW=1,000 W
Kilowatts are widely used to measure the power consumption or output of household appliances, small engines, and electric tools. For example, a typical microwave oven might use about 1 kW of power.
In electricity billing, power usage is often measured in kilowatt-hours (kWh), which reflects energy consumption over time.
The kilowatt is a practical unit for everyday energy use, bridging the scale from watts (for small devices) to megawatts (for larger power generation). It helps people understand and compare the power ratings of common electrical equipment.
Calorie (th)/hour [cal (th)/h]
The calorie (th)/hour is a unit of power measuring the rate of heat transfer in thermochemical calories per hour.
Calorie (th) refers to the thermochemical calorie, defined based on thermochemical standards, slightly different from the International Table calorie.
When expressed as cal (th)/hour, it indicates how many thermochemical calories of heat energy are transferred or generated in one hour.
