How to Convert Kilobytes to Kilobits
To convert kilobytes to kilobits, multiply by 8 then adjust for scale. This converts byte-based storage measurements to bit-based units. Related: Kilobits to Kilobytes.
KB is a byte-based unit used for measuring file sizes and storage capacity. Use our Kilobytes to Kibibits converter.
Kb is a bit-based unit—multiply bytes by 8 to get bits. You might also need: Megabits to Kilobits calculator.
1 KB = 8 Kb (using SI decimal standard) — which means there are 8kilobits in every kilobyte.
KB to Kb Conversion Formula
// Convert KB to Kb
Kb = KB × 8
// Reverse: Convert Kb to KB
KB = Kb × 0.125
KB to Kb Conversion Examples
100 KB = 800 Kb
256 KB = 2,048 Kb
500 KB = 4,000 Kb
1,000 KB = 8,000 Kb
2,048 KB = 16,384 Kb
