About this conversion
This page converts watts (W) into zeptowatts (zW), two units used to describe power, the rate at which energy is transferred or work is done.
The watt is the SI unit of power, equal to one joule per second.
A zeptowatt is 1e-21 watt units.
The formula is zW = W × 1e+21, derived from each unit's fixed relationship to the watt, the SI unit of power.
Because both units are defined by exact numeric relationships to the watt, this conversion is exact rather than approximate.
