About this conversion
This page converts gigawatts (GW) into attowatts (aW), 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 attowatt is 1e-18 watt units.
The formula is aW = GW × 1e+27, 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.
