How to Convert psi to Megapascals
To convert psi to megapascals, divide the value by 145.038.
The Formula
Megapascals = psi ÷ 145.038
Key Fact
1 megapascal = 145.038 psi
Tip: To convert megapascals back to psi, multiply by 145.038.

1 psi = 0.0069 MPa
Full precision:0.00689476 MPa
Step-by-Step Solution
To convert 1 psi to megapascals, we divide by 145.038 because one megapascal equals exactly 145.038 psi.
1 megapascal = 145.038 psi
Since there are 145.038 psi in every megapascal, we divide our value by this factor:
1 ÷ 145.038 = 0.0069 megapascals
So 1 psi = 0.0069 megapascals.
Quick check: 0.0069 × 145.038 = 1 psi
Example Conversions
Example 1: 1 psi = 0.0069 MPa
1 ÷ 145.038 = 0.0069
1 ÷ 145.038 = 0.0069
Example 2: 5 psi = 0.0345 MPa
5 ÷ 145.038 = 0.0345
5 ÷ 145.038 = 0.0345
Example 3: 10 psi = 0.0689 MPa
10 ÷ 145.038 = 0.0689
10 ÷ 145.038 = 0.0689
