Kilowatt (kW)

The kilowatt (symbol: kW) is a unit of power in the International System of Units (SI) equal to 1,000 watts:

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.

Electric Horsepower

Electric horsepower is a unit used to describe the power output of electric motors. It is closely related to the mechanical horsepower but defined slightly differently for electrical applications.

In general, 1 electric horsepower is defined as:

This value is rounded from the mechanical horsepower (745.7 W) for convenience in electrical engineering.

Electric horsepower is commonly used to rate the power of electric motors, generators, and other electrical equipment. It helps standardize comparisons between mechanical and electrical power outputs.

While watts are the SI unit of power, horsepower remains popular in motor specifications and industrial applications.
