About this calculator

MB is 1,000,000 bytes (decimal). This converter turns any value in MB into 7 other data units at once, using fixed conversion factors. Targets include B (one byte, eight bits); KB (1,000 bytes (decimal)); GB (10^9 bytes (decimal), how drives are sold).

How it works

Every result equals your value in MB multiplied by a constant. For example, 1 MB = 1,000,000 B and 1 MB = 0.00093132 GiB.

Worked example

Convert 5 MB: that is 5,000,000 B and 0.0046566 GiB.

Common mistakes

• Mixing decimal (GB) with binary (GiB) units.
• Confusing bits with bytes when reading network speeds.
• Check the unit symbol: MB is 1,000,000 bytes (decimal), so confirm your source uses that same definition.
