Watt to Nanowatt Converter

A watt (W) is the SI unit of power, defined as one joule per second. Named after Scottish inventor James Watt, it represents the rate of energy transfer and is fundamental to all power measurements in the International System of Units.

The watt was named after James Watt in 1882 and became the SI unit of power in 1960. It replaced various earlier power units and provided a unified measure based on the fundamental relationship between energy and time, becoming universal in scientific and technical applications.

Watts are universally used for all power measurements, from small electronic devices to large machinery. They're fundamental in electrical engineering, physics, energy efficiency ratings, and form the basis for all other power unit measurements.

A nanowatt (nW) is a unit of power equal to one billionth of a watt (10⁻⁹ W). It represents incredibly small amounts of power found in advanced microelectronics, quantum devices, and ultra-sensitive scientific instruments.

The nanowatt became relevant with the development of nanotechnology and quantum electronics. It provided a scale for describing power levels in quantum devices, advanced semiconductors, and ultra-sensitive measurement systems where power consumption approaches fundamental limits.

Nanowatts are used in nanotechnology, quantum electronics, ultra-sensitive instruments, and advanced research applications. They're essential for quantum device specifications, nanoelectronics, and precision scientific measurements at the molecular level.
