About Kilobyte and Kilobit
The kilobyte is an SI decimal data unit equal to exactly 1,000 bytes. Small documents, icons, and emails are commonly measured in kilobytes. The kilobit is an SI decimal data unit equal to exactly 1,000 bits, or 125 bytes. Audio bitrates and network transfer quantities are often expressed in kilobits. One Kilobyte equals 8 Kilobits (1 KB = 8 Kbit). Kilobyte is used in text documents and emails and in icons and small images. Kilobit is used in audio streaming bitrates.
Precision and Rounding:This converter keeps SI decimal prefixes (1 KB = 1,000 bytes) separate from IEC binary prefixes (1 KiB = 1,024 bytes). Match the symbol used by your source before converting because some operating-system interfaces display binary quantities with decimal labels.
See our guide to megabits vs. megabytes if you're unsure which one your download speed is quoted in.
Data units follow NIST guidance: decimal SI prefixes use powers of 1,000, while IEC binary prefixes use powers of 1,024 (reference).
