About Converting Kilowatts to Gigawatts

Kilowatt and Gigawatt both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. 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

100 kW × 0.000001 = 0.0001 GW

100 kilowatts = 0.0001 gigawatts.

Conversion table

Kilowatt (kW)Gigawatt (GW)
1 kW0.000001 GW
10 kW0.00001 GW
50 kW0.00005 GW
100 kW0.0001 GW
500 kW0.0005 GW
1,000 kW0.001 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 engineering.

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

Why do engineering unit conventions vary so much by region and industry?

Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
