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.
Joule per Hour [J/h]
Joule per hour is a unit of power measuring the rate of energy transfer or work done over time.
Joule (J) is the unit of energy or work.
When expressed as joule per hour (J/h), it measures how many joules of energy are transferred or work is done every hour.
To convert to watts (joules per second), use:
This unit is used to describe very low power levels where energy changes occur slowly over long periods.
