To convert kilowatts to gigawatts, multiply by 0.000001.
The calculation uses 1 kW = 0.000001 GW. Results are displayed to at most 10 significant digits. Definitions can be exact while a displayed decimal is rounded. Match the displayed precision to your original measurement.
The formula
kW- Input unit: kilowatts
GW- Output unit: gigawatts
How to use this calculator
- Enter a value in kW.
- Multiply by the stored conversion factor.
- Read the result in GW; divide by the same factor to convert back.
Worked examples
Worked conversion
1 kW × 0.000001 ≈ 0.000001 GW.
Reverse conversion
0.000001 GW ÷ 0.000001 ≈ 1 kW. Rounding intermediate values can change the last displayed digit.
Frequently asked questions
What factor does this converter use?
It uses 0.000001 GW per kW.
Why can another converter show a slightly different answer?
Check the unit convention first (such as US versus Imperial or decimal versus binary), then compare rounding. Measurement uncertainty is separate from the unit conversion.
