# Kilopascals to Pascals (kPa to Pa)

> Convert kilopascals to pascals: 1 kPa = 1000 Pa. Exact conversion factor, formula, 22-row table and worked examples, with JSON API and MCP access.

- Page id: `kpa-to-pa` · Quantity: Pressure (`pressure`, base unit Pa) · Tool: `convert_units`
- Canonical page: https://tttkmbb.com/conversion/kpa-to-pa · This document: https://tttkmbb.com/conversion/kpa-to-pa.md · JSON: https://tttkmbb.com/conversion/kpa-to-pa.json (add `?value=` for a result)

## Formula

- `1 kPa = 1000 Pa`
- `pascals = kilopascals × 1000`
- Reverse: `kilopascals = pascals × 0.001`

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 kPa = 5000 Pa
- 12.5 kPa = 12500 Pa
- 100 kPa = 100000 Pa

## FAQ

**How many pascals are in one kilopascal?**

1 kPa = 1000 Pa. 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 kilopascals to pascals?**

Multiply the value in kilopascals by 1000: pascals = kilopascals × 1000. For example, 5 kPa = 5000 Pa.

**How do I convert pascals back to kilopascals?**

Multiply by the inverse factor 0.001 (kilopascals = pascals × 0.001), or use the pascals-to-kilopascals page.
