About this conversion
This page converts kilowatts (kW) into femtowatts (fW), two units used to describe power, the rate at which energy is transferred or work is done.
A kilowatt is 1000 watt units.
A femtowatt is 1e-15 watt units.
The formula is fW = kW × 1e+18, 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.
