GWh vs MWh: Scaling Up to National Grid Energy Metrics
When Megawatt-hours become too small: comparing Gigawatt-hours (GWh) and Terawatt-hours (TWh) for national energy statistics.

Scaling Units: Wh to TWh
- 1 Kilowatt-hour (kWh): 1,000 Wh
- 1 Megawatt-hour (MWh): 1,000,000 Wh = 1,000 kWh
- 1 Gigawatt-hour (GWh): 1,000,000,000 Wh = 1,000 MWh
- 1 Terawatt-hour (TWh): 1,000,000,000,000 Wh = 1,000 GWh
