Convert kilowatt [kW] to nanowatt [nW] Online | Free power Converter

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.

Nanowatt (nW)

The nanowatt (symbol: nW) is a unit of power in the International System of Units (SI) equal to one-billionth of a watt:

The prefix "nano-" means one-billionth, so nanowatts measure extremely small amounts of power. This unit is useful in very sensitive electronic devices, ultra-low-power circuits, and certain scientific instruments.

For example, the power consumption of some microelectronic components or very faint signals can be measured in nanowatts.

Nanowatts help quantify minuscule power levels that would be cumbersome to express with larger units, making them important in precision technology and research.
