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.

Attowatt (aW)

The attowatt (symbol: aW) is a unit of power in the International System of Units (SI) equal to one-quintillionth of a watt:

The prefix "atto-" means one-quintillionth, so attowatts measure unbelievably tiny amounts of power. This scale is used in extremely sensitive scientific research, such as quantum computing, ultra-low power electronics, and detecting very weak signals in astrophysics.

For example, some measurements of single-photon detectors or nanoscale devices may involve power levels in the attowatt range.

Attowatts allow scientists to quantify and analyze power at the most minute levels, essential for the frontier of modern technology and physics.
