How to Convert Megapascal to Pascal
- 1 MPa = 1000000 Pa
- 1 Pa = 0.000001 MPa
- Example: convert 15 MPa to Pa: 15 MPa = 15 × 1000000 Pa = 15000000 Pa
Formula
Pa = MPa × 1000000
Derivation from SI units:
- 1 MPa = 10⁶ Pa = 1 N/mm²
- 1 Pa = 1 N/m² = 1 kg·m⁻¹·s⁻²
Both units are defined exactly, so the factor is exact. Megapascal definition: megapascal; Pascal definition: pascal.
Worked examples
- A reading of 2 MPa converts to 2000000 Pa.
2 MPa × 1000000 = 2000000 Pa - A value of 30 MPa is 30000000 Pa.
30 MPa × 1000000 = 30000000 Pa

Where it's used
Megapascals are used for concrete compressive strength (typically 20–50 MPa), while pascals appear in cleanroom and isolator pressure differentials (typically 10–50 Pa). Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
