# Newtons to Kilonewtons (N to kN)

> Convert newtons to kilonewtons: 1 N = 0.001 kN. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.

- Page id: `newtons-to-kilonewtons` · Quantity: Force (`force`, base unit N) · Tool: `convert_units`
- Canonical page: https://tttkmbb.com/conversion/newtons-to-kilonewtons · This document: https://tttkmbb.com/conversion/newtons-to-kilonewtons.md · JSON: https://tttkmbb.com/conversion/newtons-to-kilonewtons.json (add `?value=` for a result)

## Formula

- `1 N = 0.001 kN`
- `kilonewtons = newtons × 0.001`
- Reverse: `newtons = kilonewtons × 1000`

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

- 5 N = 0.005 kN
- 12.5 N = 0.0125 kN
- 100 N = 0.1 kN

## FAQ

**How many kilonewtons are in one newton?**

1 N = 0.001 kN. 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 newtons to kilonewtons?**

Multiply the value in newtons by 0.001: kilonewtons = newtons × 0.001. For example, 5 N = 0.005 kN.

**How do I convert kilonewtons back to newtons?**

Multiply by the inverse factor 1000 (newtons = kilonewtons × 1000), or use the kilonewtons-to-newtons page.
