About this conversion

This page converts gigawatts (GW) into zettawatts (ZW), two units used to describe power, the rate at which energy is transferred or work is done.

A gigawatt is 1e+09 watt units.

A zettawatt is 1e+21 watt units.

The formula is ZW = GW × 1e-12, 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.
