Convert femtowatt to watt
Please provide values below to convert femtowatt [fW] to watt [W], or Convert watt to femtowatt.
1 fW = 1.0000e-15 W. To convert femtowatt to watt, multiply the value by 1.0000e-15; to go the other way, divide by it (1 W = 1.0000e+15 fW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 fW = 1.0000e-15 W
- 1 W = 1.0000e+15 fW
- 10 fW = 1.0000e-14 W
- 100 fW = 1.0000e-13 W
How to Convert Femtowatt to Watt
1 fW = 1e-15 W
Example: convert 15 fW to W:
15 fW = 15 × 1e-15 W = 1.5e-14 W

Femtowatt
A femtowatt (fW) is a unit of power equal to 10^-15 watts, representing an extremely small amount of power.
History/Origin
The femtowatt was introduced as part of the SI prefixes to measure very small quantities of power, particularly in scientific and technological contexts, gaining recognition as the need to quantify minute power levels grew.
Current Use
Femtowatts are used in fields such as quantum physics, nanotechnology, and optical measurements, where precise measurement of extremely low power levels is required.
Watt
The watt (W) is the SI unit of power, defined as one joule per second, representing the rate of energy transfer or conversion.
History/Origin
The watt was named after James Watt, the Scottish engineer and inventor, in 1889. It was adopted as the SI unit of power to standardize measurements in science and engineering.
Current Use
The watt is widely used today to quantify power in electrical devices, engines, and energy consumption, serving as a fundamental unit in physics, engineering, and everyday applications.
