How to Convert Kilopascal to Megapascal
- 1 kPa = 0.001 MPa
- 1 MPa = 1000 kPa
- Example: convert 15 kPa to MPa: 15 kPa = 15 × 0.001 MPa = 0.015 MPa
Formula
MPa = kPa ÷ 1000
Derivation from SI units:
- 1 kPa = 10³ Pa
- 1 MPa = 10⁶ Pa = 1 N/mm²
- 1 kPa = 1000 Pa ÷ 1000000 Pa per MPa = 0.001 MPa
Both units are defined exactly, so the factor is exact. Kilopascal definition: kilopascal; Megapascal definition: megapascal.
Worked examples
- A reading of 20 kPa converts to 0.02 MPa.
20 kPa × 0.001 = 0.02 MPa - A value of 300 kPa is 0.3 MPa.
300 kPa × 0.001 = 0.3 MPa

Where it's used
Kilopascals are used for tyre pressure outside the United States (about 200–250 kPa for cars), while megapascals appear in concrete compressive strength (typically 20–50 MPa). Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.

Frequently asked questions
How many megapascals are in 1 kilopascal?
1 kPa = 0.001 MPa.
How do I convert kilopascals to megapascals?
Multiply the value in kPa by 0.001, or divide it by 1000. For example, 15 kPa × 0.001 = 0.015 MPa.
Is the kPa to MPa conversion exact?
Yes. Both units are defined exactly, and 1 kPa is exactly 0.001 MPa.
