How does the data storage converter work?

All storage units are stored relative to bytes. The calculator converts your value to bytes, then to the target unit, so kilobytes, megabytes, gigabytes, and terabytes convert accurately.

How many MB are in a GB?

In the decimal convention, 1 GB = 1,000 MB; in the binary convention, 1 GiB = 1,024 MiB. This converter offers both, since storage devices advertise decimal while operating systems often report binary.

What is the difference between GB and GiB?

A gigabyte (GB) uses powers of 1,000 (10⁹ bytes), while a gibibyte (GiB) uses powers of 1,024 (2³⁰ bytes). A 1 TB drive shows as about 931 GB in some systems because of this difference.

How many bytes are in a kilobyte?

Technically 1,024 bytes in the binary convention, though some contexts use 1,000. The converter shows both interpretations so you understand the figure you see.

Which units should I use for file sizes?

For practical file sizes, megabytes (MB) and gigabytes (GB) are standard for most users, with terabytes (TB) for larger storage. The converter supports from bytes up to petabytes.

How It Works

Decimal: 1 KB = 1,000 B, 1 MB = 1,000 KB (drive marketing)
Binary: 1 KiB = 1,024 B (what OS reports)

Example: 1 GB = 1,000 MB (decimal). A 1 TB drive often shows ~931 GB in the operating system.
