# Kibibytes to Kilobytes (KiB to KB)

> Convert kibibytes to kilobytes: 1 KiB = 1.024 KB. Exact conversion factor, formula, 18-row table and worked examples, with JSON API and MCP access.

- Page id: `kib-to-kb` · Quantity: Data storage (`data-storage`, base unit B) · Tool: `convert_units`
- Canonical page: https://tttkmbb.com/conversion/kib-to-kb · This document: https://tttkmbb.com/conversion/kib-to-kb.md · JSON: https://tttkmbb.com/conversion/kib-to-kb.json (add `?value=` for a result)

## Formula

- `1 KiB = 1.024 KB`
- `kilobytes = kibibytes × 1.024`
- Reverse: `kibibytes = kilobytes × 0.9765625`

The factor follows from the SI definitions of both units (NIST SP 811); values below are rounded to 6 significant figures, the API returns up to 12.

## Worked examples

- 1.5 KiB = 1.536 KB
- 700 KiB = 716.8 KB
- 2048 KiB = 2097.15 KB

## FAQ

**How many kilobytes are in one kibibyte?**

1 KiB = 1.024 KB. The factor comes from the SI definitions of both units (NIST SP 811 / BIPM), so it is exact or correct to at least 10 significant figures.

**What is the formula to convert kibibytes to kilobytes?**

Multiply the value in kibibytes by 1.024: kilobytes = kibibytes × 1.024. For example, 1.5 KiB = 1.536 KB.

**How do I convert kilobytes back to kibibytes?**

Multiply by the inverse factor 0.9765625 (kibibytes = kilobytes × 0.9765625), or use the kilobytes-to-kibibytes page.
