kWtoGW

Convert kilowatts (kW) to gigawatts (GW).

Factor1 kW = 1e-6 GW

Converter

kW

Accepts numbers or expressions, e.g. 150 + 14.7

Result
1GW

Rendered to 6 significant figures.

Formula

Formula
GW = kW × 1e-6

Multiply any value in kilowatts by 1e-6 to obtain the value in gigawatts.

Worked example

Convert 1.00000e+6 kW to GW.

  1. 01Start with 1.00000e+6 kW.
  2. 02Multiply by the conversion factor: 1.00000e+6 × 1e-6 = 1 GW.
Result1.00000e+6 kW = 1 GW

FAQ

What is the conversion factor from kW to GW?
1 kW equals 1e-6 GW. To convert, multiply the value in kilowatts by 1e-6.
How do I convert 1 kW to GW?
1 kW = 1e-6 GW. For any value, multiply by 1e-6.
How do I convert GW back to kW?
Divide by the same factor — or equivalently, multiply by 1000000. So 1 GW = 1.00000e+6 kW.
When would I need to convert kilowatt to gigawatt?
Power conversions are common when comparing motor ratings (often kW or hp), thermal duty (BTU/hr or kW), and utility consumption in mixed-unit projects.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
