Conversion Formula
The formula to convert psi to MPa is: MPa = psi × 0.00689476. This works because 1 psi equals 0.00689476 MPa in pressure units. To convert, multiply the given psi value by this factor. For example, 40 psi × 0.00689476 = 0.2758 MPa.
Conversion Example
- Convert 20 psi to MPa:
- Step 1: Write the formula: MPa = 20 × 0.00689476
- Step 2: Multiply: 20 × 0.00689476 = 0.1379 MPa
- Step 3: Result: 20 psi = 0.1379 MPa
- Convert 55 psi to MPa:
- Step 1: Write the formula: MPa = 55 × 0.00689476
- Step 2: Multiply: 55 × 0.00689476 = 0.3792 MPa
- Step 3: Result: 55 psi = 0.3792 MPa
- Convert 15 psi to MPa:
- Step 1: Write the formula: MPa = 15 × 0.00689476
- Step 2: Multiply: 15 × 0.00689476 = 0.1034 MPa
- Step 3: Result: 15 psi = 0.1034 MPa

Conversion Definitions
psi
Psi, or pounds per square inch, measures pressure based on the force exerted by one pound of force on a one-square-inch area. It is used mainly in imperial systems for pressure, especially in the United States, to quantify gases or liquids in various applications.
mpa
Megapascal (MPa) is a metric unit of pressure equal to one million pascals. It quantifies force per area, often used in engineering, material science, and fluid mechanics to describe stress, pressure, or load with precise, standardized measurement.
