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.

Terawatt (TW)

The terawatt (symbol: TW) is a unit of power in the International System of Units (SI) equal to $10^{12}$ watts:

Terawatts measure very large amounts of power and are commonly used to describe global-scale energy production or consumption. For instance, the total worldwide electricity consumption is often expressed in terawatts.

To put it in perspective, one terawatt equals one trillion watts, which is about a million times the power of a typical household light bulb.

Terawatts are also used in describing the power output of large power plants, energy resources, or the total energy produced by the sun reaching the Earth.

Overall, the terawatt is a key unit when discussing energy on planetary or industrial scales.
