How to convert kilowatt-hours to gigawatt-hours?

To convert kilowatt-hours (kWh) to gigawatt-hours (GWh), you need to understand the relationship between the units:

1 kilowatt (kW) = 10310^3 watts (W) 1 megawatt (MW) = 10610^6 watts (W) 1 gigawatt (GW) = 10910^9 watts (W)

Similarly, 1 kilowatt-hour (kWh) = 10310^3 watt-hours (Wh) 1 megawatt-hour (MWh) = 10610^6 watt-hours (Wh) 1 gigawatt-hour (GWh) = 10910^9 watt-hours (Wh)

Therefore, 1 gigawatt-hour (GWh) = 10610^6 kilowatt-hours (kWh)

To convert kilowatt-hours to gigawatt-hours, you divide the number of kilowatt-hours by 10610^6 (or 1,000,000).

So, to convert 1 kilowatt-hour to gigawatt-hours:

1 kWh=1 kWh106 GWh=1×106 GWh=0.000001 GWh1 \text{ kWh} = \frac{1 \text{ kWh}}{10^6} \text{ GWh} = 1 \times 10^{-6} \text{ GWh} = 0.000001 \text{ GWh}

Real-World Examples:

  1. Household Energy Consumption:

    • Average U.S. household electricity consumption is about 877 kWh per month.
    • In gigawatt-hours: 877 kWh×1 GWh106 kWh=0.000877 GWh877 \text{ kWh} \times \frac{1 \text{ GWh}}{10^6 \text{ kWh}} = 0.000877 \text{ GWh}
  2. Small Business Consumption:

    • A small business might consume around 30,000 kWh per month.
    • In gigawatt-hours: 30,000 kWh×1 GWh106 kWh=0.03 GWh30,000 \text{ kWh} \times \frac{1 \text{ GWh}}{10^6 \text{ kWh}} = 0.03 \text{ GWh}
  3. Large Industrial Facility:

    • A large industrial facility might consume 5,000,000 kWh per month.
    • In gigawatt-hours: 5,000,000 kWh×1 GWh106 kWh=5 GWh5,000,000 \text{ kWh} \times \frac{1 \text{ GWh}}{10^6 \text{ kWh}} = 5 \text{ GWh}
  4. City Consumption:

    • A small city might consume around 200,000,000 kWh per year.
    • In gigawatt-hours: 200,000,000 kWh×1 GWh106 kWh=200 GWh200,000,000 \text{ kWh} \times \frac{1 \text{ GWh}}{10^6 \text{ kWh}} = 200 \text{ GWh}
  5. Nationwide Consumption:

    • The entire United States consumed approximately 4,000,000,000,000 kWh (4 trillion kWh) in a year.
    • In gigawatt-hours: 4,000,000,000,000 kWh×1 GWh106 kWh=4,000,000 GWh4,000,000,000,000 \text{ kWh} \times \frac{1 \text{ GWh}}{10^6 \text{ kWh}} = 4,000,000 \text{ GWh}

Understanding these conversions helps in making sense of the energy consumption at different scales, from small households to entire nations.

What is kilowatt-hours?

A Kilowatt-hour is a unit of energy and its units, kWh, are formed with W for watt and h for hour from SI unit system combined with letter k, metric prefix, for 1,000 or 10310^3. Its definition, in the context of electricity, is the energy of one watt power flowing for one hour.

Followings equivalent equations are identical but in different units. Please note that factor 10310^3 is representing Kilo prefix in kWh unit.

What is gigawatt-hours?

A Gigawatt-hour is a unit of energy and its units, GWh, are formed with W for watt and h for hour from SI unit system combined with letter G, metric prefix, for 1,000,000,000 or 10910^9. Its definition, in the context of electricity, is the energy of one watt power flowing for one hour.
