Petawatt
A petawatt (PW) is a unit of power equal to 10^15 watts, used to measure extremely high power levels.
History/Origin
The petawatt was introduced in the 1980s as part of the SI prefixes to describe ultra-high power outputs, particularly in laser physics and astrophysics research.
Current Use
Petawatts are primarily used in scientific research involving high-intensity lasers, astrophysics, and nuclear physics to quantify extremely large power outputs.
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.
