Conversion Formula
To convert psi to pa, multiply the psi value by 6894.76. This number is the exact conversion factor because one pound-force per square inch equals 6894.76 newtons per square meter, which is the pascal unit.
Formula:
Pressure (pa) = Pressure (psi) × 6894.76
For example, converting 14.7 psi:
- Take 14.7 psi
- Multiply by 6894.76
- 14.7 × 6894.76 = 101352.972 pa
This conversion works by using the defined equivalence between the imperial unit psi and SI unit pascal.

- Start with 5 psi
- Multiply 5 × 6894.76
- Result: 34473.8 pa
- Convert 20 psi to pa:
- Take 20 psi
- Calculate 20 × 6894.76
- Result: 137895.2 pa
- Convert 0.5 psi to pa:
- Start with 0.5 psi
- Multiply 0.5 × 6894.76
- Result: 3447.38 pa
- Convert 100 psi to pa:
- Take 100 psi
- Multiply 100 × 6894.76
- Result: 689476 pa

Conversion Definitions
psi: Psi, or pounds per square inch, is a pressure unit representing the force of one pound-force applied to an area of one square inch. It’s commonly used in the United States for tire pressure, hydraulics, and other applications where imperial units are preferred.
pa: Pascal (pa) is the SI unit of pressure defined as one newton per square meter. It measures force per unit area, used worldwide in science and engineering fields for pressure measurement with metric system standardization.
Conversion FAQs
Why does the conversion factor from psi to pascals equal 6894.76?
The conversion factor 6894.76 arises because 1 psi means 1 pound-force on 1 square inch. When converted into SI units, pound-force converts to newtons and square inches convert to square meters. Multiplying these unit conversions gives exactly 6894.76.pa per psi.
Can I convert psi to pa without a calculator?
You can approximate by multiplying psi value by about 6900 to get pascals quickly. This gives a close estimate but for precise calculations, using 6894.76 is recommended. Handy for rough conversions but less accurate.
Is 14.7 psi atmospheric pressure in pascals?
Yes, 14.7 psi is roughly atmospheric pressure at sea level. Converted to pascals, it equals approximately 101352.75 pa, which is close to the standard atmospheric pressure of 101325 pa used in scientific contexts.
What happens if psi values are negative when converting to pa?
Negative psi values mean pressure below atmospheric or vacuum conditions. The same conversion applies, multiplying by 6894.76, resulting in negative pascal values representing negative gauge pressures.
Is pascal always a smaller unit than psi?
Yes, pascal is smaller unit. One psi equals thousands of pascals. So, when converting, psi values become much larger numbers in pascals due to the size difference between the units.
