Data Storage Converter
Convert digital storage units from bits to terabytes.
Megabytes (MB)
1,000
1 Gigabytes (GB)
Bits
8,000,000,000
Bytes (B)
1,000,000,000
Kilobytes (KB)

Decimal (SI) units use powers of 1,000 — common on drive packaging and network specs.
In-depth explanation
Convert between bits, bytes, and storage units in two modes: Decimal (KB/MB/GB, powers of 1,000) and Binary (KiB/MiB/GiB, powers of 1,024) — handy when OS “GB” and drive-label “GB” disagree. Everything runs locally in your browser — your inputs are not uploaded to produce the result.
GB usually means 1,000³ bytes (decimal). GiB means 1,024³ bytes (binary). Hard-drive marketing often uses decimal; many operating systems report binary. There are 8 bits in 1 byte.
In this tool, MB is decimal (1,000 KB) and MiB is binary (1,024 KiB). Check which label you’re converting. Tweak the inputs above to compare options, then copy or note the result you need.
Drive boxes often use decimal GB (1,000³ bytes); operating systems often show GiB (1,024³). That is why a “256 GB” SSD looks smaller in the finder. Bits vs bytes is an 8× trap on network speeds.
Pick Decimal or Binary mode and stay there for the whole comparison. MB vs MiB is labelled on purpose. This will not recover files; it only converts quantities.
