Convert Gigawatt-hours to Kilowatt-hours

To convert gigawatt-hours to kilowatt-hours, the value is multiplied by the exact conversion factor 1000000 — that is, 1 gigawatt-hours = 1000000 kilowatt-hours. This tool applies that reference factor so results are precise.

• 1

  This page converts Gigawatt-hours to Kilowatt-hours using the exact reference factor 1000000. That is the standard figure, so the results here match reference tables rather than rounded approximations.

• 2

  Sanity-check the Gigawatt-hours to Kilowatt-hours result by converting it back in the opposite direction; landing on your original input confirms both the direction and the 1000000 factor were right before you rely on the number.

• 3

  Enter plain decimal numbers without thousand separators: a comma can be read as a decimal mark in some locales and silently change the magnitude of the Gigawatt-hours value you meant to convert to Kilowatt-hours.

• Decimal separators corrupt input silently: a comma can be read as a thousands separator and shift a Gigawatt-hours value by ×1000. Control check: enter 2.5 and confirm the result equals 2500000 Kilowatt-hours before trusting larger values.

• Order-of-magnitude check: 1 Gigawatt-hour = 1000000 Kilowatt-hour exactly, so type 1 first — a wildly different kilowatt-hours figure means a stray comma, wrong field, or flipped direction before you convert real values.
