Convert between bits, bytes, kilobytes, megabytes, gigabytes, terabytes and more — instantly and accurately.
In the decimal (SI) system, 1 kilobyte = 1,000 bytes. Hard drive manufacturers and network speeds use this standard. In the binary (IEC) system, 1 kibibyte = 1,024 bytes — the standard used by operating systems when reporting RAM and file sizes.
This converter supports both systems. Pick the one that matches your context for an accurate result.
