About Converting Kilowatts to Gigawatts
Kilowatt and Gigawatt both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. Kilowatt is most often used for electric vehicle motor power ratings (alongside horsepower).
Formula
gigawatts = kilowatts × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 kilowatt equals 1000 base units, and 1 gigawatt equals 1000000000 base units, so dividing one by the other gives the direct kilowatt-to-gigawatt factor of 0.000001.
Simple example
1 kW × 0.000001 = 0.000001 GW
1 kilowatt = 0.000001 gigawatts.
Real-world example
120 kW × 0.000001 = 0.00012 GW
120 kilowatts = 0.00012 gigawatts.
Conversion table
| Kilowatt (kW) | Gigawatt (GW) |
|---|---|
| 1 kW | 0.000001 GW |
| 5 kW | 0.000005 GW |
| 12 kW | 0.000012 GW |
| 24 kW | 0.000024 GW |

Reverse conversion: Gigawatt to Kilowatt
0.000001 GW × 1000000 = 1 kW
0.000001 gigawatts = 1 kilowatt.
kilowatts = gigawatts × 1000000

Understanding the Kilowatt
Kilowatt (kW) measures power. A kilowatt is 1,000 watts. It is classified as a SI derived (metric prefix) unit.
Where it's used: Standard power unit worldwide for larger appliances, vehicles, and electrical systems
Uses of the Kilowatt today
- Electric vehicle motor power ratings (alongside horsepower)
- Household electrical system and generator capacity
- Industrial motor and equipment power ratings
History of the Kilowatt
The kilowatt follows directly from the watt via the standard SI 'kilo-' prefix, becoming especially prominent with the growth of electrical power generation and distribution in the late 19th and 20th centuries.
Historical origin. Kilowatt was not the invention of a single named person; it developed through the process described above.
Understanding the Gigawatt (GW)
Gigawatt is 1000000000 watt units.
Kilowatt — sources
- BIPM SI Brochure — SI prefixes — Defines 'kilo-' as the prefix for 10³.

Frequently asked questions
How many gigawatts are in 1 kilowatt?
1 kilowatt equals 0.000001 gigawatts, using the exact defined conversion factor rather than an estimate.
How do I convert kilowatt to gigawatt?
Multiply the kilowatt value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert gigawatt back to kilowatt?
Use the reverse factor: 1 gigawatt equals 1,000,000 kilowatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilowatt?
Kilowatt (kW) measures power. A kilowatt is 1,000 watts. It is classified as a SI derived (metric prefix) unit.
What is a gigawatt?
Gigawatt (GW) is a unit of electricity.
Is the kilowatt to gigawatt conversion exact?
Yes. Both kilowatt and gigawatt are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 used above is exact to as many digits as you choose to display.
Where is the kilowatt still used today?
Standard power unit worldwide for larger appliances, vehicles, and electrical systems
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
