Data Storage Units

Convert between bits, nibbles, bytes and larger units, with every intermediate step shown and all equivalents in one table.

Base:

1 KB = 1,000 bytes · 1 MB = 1,000 KB · etc.

Value

Convert FROM

Convert TO

Result:1,000MB(1 GB → 1,000 MB)

1Step-by-Step Conversion

1GB

↓× 1,000

(1 GB = 1,000 MB)

1,000MB

How it works

× multiply (going to a smaller unit)

One large unit contains many small units, so the number increases when converting down.

Conversion factors

1 nibble = 4 bits

1 byte = 2 nibbles = 8 bits

1 KB = 1,000 bytes

Each larger unit = 1,000 × the one below
