PSI to Newton per Square Meter Conversion
1 PSI = 6894.76 N/m² (Pascals)
1 N/m² = 0.000145038 PSI
N/m² = PSI × 6894.76
PSI = N/m² × 0.000145038
Convert 10 PSI to Newton per Square Meter:
N/m² = PSI × 6894.76
N/m² = 10 × 6894.76
N/m² = 68947.6 (with 1 decimal place)
Convert 100000 N/m² to PSI:
PSI = N/m² × 0.000145038
PSI = 100000 × 0.000145038
PSI = 14.5038 (with 4 decimal places)
Note: These conversions use the exact factor of 1 PSI = 6894.75729 N/m² (rounded to 6894.76 for practical use)

Common questions about PSI, Newton per Square Meter, and pressure measurements.
One PSI (pound per square inch) is equal to 6894.76 Newtons per square meter (Pascals). This conversion factor is derived from the definition of PSI and the SI unit system:
1 PSI = 6894.76 N/m² (Pa)
1 N/m² = 0.000145038 PSI
N/m² = PSI × 6894.76
PSI = N/m² × 0.000145038
The exact conversion factor is 6894.75729 N/m² per PSI, which is rounded to 6894.76 for practical engineering and industrial applications.
PSI and Pascals (N/m²) are both units of pressure but belong to different measurement systems:
This converter provides accurate conversions between these two units for all pressure measurement needs.
These pressure units are used in different contexts and regions:
International companies often need to convert between these units for global operations and compliance with different regional standards.
Precision in pressure conversions is critical for safety, performance, and compliance in many industries:
This converter defaults to 2 decimal places, which provides sufficient precision for most industrial and consumer applications. For critical engineering applications, you can adjust up to 4 decimal places for higher accuracy.
Understanding key reference points helps in practical pressure measurements:
Note that pressure measurements can be gauge (relative to atmospheric) or absolute (relative to vacuum), which is important for accurate conversions in technical applications.
