About this conversion
This page converts zettawatts (ZW) into petawatts (PW), two units used to describe power, the rate at which energy is transferred or work is done.
A zettawatt is 1e+21 watt units.
A petawatt is 1e+15 watt units.
The formula is PW = ZW × 1000000, 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.
