Work out megabyte to gigabyte instantly with clear inputs, formula shown and shareable results.
Converting Megabytes to Gigabytes is one multiplication: a single MB is 0.001 GB, so the amount is scaled by that factor. Reversing the direction divides by the same factor. The factor is an exact definition rather than a rounded figure, so the result stays precise at any magnitude. Storage manufacturers use decimal gigabytes; operating systems often report gibibytes, which are 7.4% larger.
Megabytes → Gigabytes
GB = MB × 0.001
Gigabytes → Megabytes
MB = GB ÷ 0.001
One MB equals 0.001 GB. That value is exact by definition.
Divide by 0.001 rather than multiplying, or flip the direction selector which does it for you.
