Convert megabytes to gigabytes, bytes to bits, and decimal or binary storage units. Compare KB, MB, GB, TB, KiB, MiB, GiB, and TiB without floating-point input rounding.
KB, MB, GB, and TB use powers of 1,000. KiB, MiB, GiB, and TiB use powers of 1,024. One byte is eight bits.
One gigabyte (GB) equals 1,000 megabytes (MB), so divide MB by 1,000 to get GB. For example, 1,500 MB equals 1.5 GB. Binary units are different: one gibibyte (GiB) equals 1,024 mebibytes (MiB). Select MiB and GiB when a system uses binary sizes instead of treating MB as an ambiguous 1,024-based unit.
A byte contains eight bits. File sizes usually use bytes, while network speeds often use bits per second; this tool converts quantities, not transfer durations. Calculations preserve decimal input as exact integer ratios, including large amounts. Results with more than 12 decimal places are rounded and marked approximate, and extremely small positive values are shown with a less-than threshold instead of zero.
