Convert Watts to Petawatts
Please provide values below to convert Watts [W] to Petawatts [PW].
How to Convert Watts to Petawatts
1 W = 1e-15 PW
1 PW = 1000000000000000 W
Example: convert 10 W to PW: 10 W = 10 × 1e-15 W = 1e-14 W
Watts
Definition: A watt (W) is the SI unit of power, defined as one joule per second (1 J/s). It represents the rate at which energy is transferred or converted.
History: The watt is named after Scottish engineer **James Watt**, whose work on steam engines revolutionized energy efficiency. It was officially adopted as the unit of power in the **International System of Units (SI)** in 1960 and is widely used in electricity, mechanics, and thermodynamics.
Petawatts
Definition: A petawatt (PW) is a unit of power equal to 10¹⁵ watts, commonly used in astrophysics and high-energy laser physics.
History: The petawatt is used to measure extremely large power levels, such as those in **solar radiation, astrophysical events, and high-energy laser experiments**. The most powerful laser pulses in the world can reach petawatt levels for short bursts of time.
