• 1

  This page converts Megawatt-hours to Gigajoules using the exact reference factor 3.6. That is the standard figure, so the results here match reference tables rather than rounded approximations.

• 2

  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 Megawatt-hours value you meant to convert to Gigajoules.

• 3

  Round only the final result: keep full precision while converting Megawatt-hours to Gigajoules and round once at the end, because rounding every intermediate step lets drift accumulate until the final figure drifts from its true value.

• Round-trip check: convert your megawatt-hours figure to gigajoules, then convert back with the reverse tool — landing on the original number confirms both direction and factor. Skipping this check is how a flipped ratio survives into reports and homework.

• Order-of-magnitude check: 1 Megawatt-hour = 3.6 Gigajoule exactly, so type 1 first — a wildly different gigajoules figure means a stray comma, wrong field, or flipped direction before you convert real values.
