Free online data storage converter. Convert between bits, nibbles, bytes, kilobits, kibibits, kilobytes, megabytes, gigabytes, terabytes and more binary/decimal units.
Data storage units can be confusing — especially when you mix decimal (kilobytes where 1 KB = 1000 bytes) with binary (kibibytes where 1 KiB = 1024 bytes). Hard drive manufacturers use decimal, while operating systems use binary. That's why your "1 TB" drive shows up as 931 GB on your computer.
Our data storage converters handle both systems:
Decimal (SI) Units
- Bits to Kilobytes
- Bits to Megabytes
- Bits to Gigabytes
- Bits to Terabytes
- Bytes to Megabytes
- Bytes to Gigabytes
- Bytes to Terabytes
Binary (IEC) Units
- Bits to Kibibytes
- Bits to Mebibytes
- Bits to Gibibytes
- Bits to Tebibytes
- Bytes to Mebibytes
- Bytes to Gibibytes
Plus nibble (4 bits) conversions and every combination up to yottabytes and yobibytes. Whether you're calculating storage needs, comparing cloud plans, or just satisfying curiosity, it's all covered.
