Converter for data
Convert between bytes, KB, MB, GB, TB using decimal (SI) units and KiB, MiB, GiB using binary (IEC) units. You can also switch between bits and bytes.
Quick data converters
-
KB ↔ MB (decimal)
Decimal (SI):
1 MB = 1000 KB -
MB ↔ GB (decimal)
Decimal (SI):
1 GB = 1000 MB -
Bytes ↔ KB (decimal)
Decimal (SI):
1 KB = 1000 bytes -
Bytes ↔ KiB (binary)
Binary (IEC):
1 KiB = 1024 bytes
Tip: Operating systems often report storage in decimal (1000-based) units, while RAM and some software use binary (1024-based) units.
Common data conversions (examples)
| KB (decimal) | MB |
|---|---|

Data conversion FAQs
What’s the difference between KB and KiB?
KB (kilobyte) uses decimal (SI) where 1 KB = 1000 bytes. KiB (kibibyte) uses binary (IEC) where 1 KiB = 1024 bytes.
Why does my disk show fewer GB than advertised?
Manufacturers use decimal (1 GB = 1,000,000,000 bytes). Some operating systems show binary GiB (1 GiB = 1,073,741,824 bytes), so the number looks smaller.
Are bits and bytes the same?
No. 1 byte = 8 bits. Network speeds (e.g., Mbps) are in bits per second; file sizes are usually in bytes.
