Conversion Formula
The conversion formula from psi to pascals is:
Pressure (pa) = Pressure (psi) × 6894.76
This formula works because 1 psi equals exactly 6894.76 pascals. The psi unit measures pressure based on pounds force per square inch, while pascal measures pressure in newtons per square meter.
Example calculation for 14.7 psi:
- Multiply 14.7 by 6894.76
- 14.7 × 6894.76 = 101352.94 pa
- Result: 101352.94 pascals
Conversion Example
- Convert 5 psi to pa:
- Multiply 5 by 6894.76
- 5 × 6894.76 = 34473.8 pa
- Result: 34473.8 pascals
- Convert 20 psi to pa:
- Multiply 20 by 6894.76
- 20 × 6894.76 = 137895.2 pa
- Result: 137895.2 pascals
- Convert 0 psi to pa:
- Multiply 0 by 6894.76
- 0 × 6894.76 = 0 pa
- Result: 0 pascals
- Convert 7.5 psi to pa:
- Multiply 7.5 by 6894.76
- 7.5 × 6894.76 = 51710.7 pa

Conversion Definitions
psi: Psi stands for pounds per square inch, a unit measuring pressure. It expresses the force in pounds applied on an area of one square inch. This unit is common in the US for tire pressure, hydraulics, and other applications where pressure forces are measured in imperial units.
pa: Pascal (pa) is the SI unit of pressure, equal to one newton per square meter. It quantifies force over area in metric units. Pa is widely used in science and engineering to measure pressure in gases, liquids, and solids, providing a standard metric reference.
Conversion FAQs
Why is 1 psi equal to 6894.76 pascals?
1 psi equals 6894.76 pascals because psi is based on pounds-force per square inch, and pascal is newtons per square meter. The conversion factor comes from converting pounds-force to newtons and square inches to square meters, resulting in the exact multiplier 6894.76.
Can psi values be negative, and what does that mean in pascals?
Yes, psi values can be negative, indicating pressure below atmospheric pressure, often called vacuum pressure. When converted to pascals, negative psi becomes negative pa, representing lower pressure relative to atmospheric baseline.
Is the conversion from psi to pa exact or approximate?
The conversion factor 6894.76 is exact based on defined units. However, rounding during calculations can cause small approximations. Using more decimals increases precision but for most applications, 6894.76 is sufficiently accurate.
Why do some sources use 6895 instead of 6894.76 for conversion?
Some use 6895 as a rounded conversion factor for simplicity, but it’s less precise. The exact number is 6894.76, which comes from official unit definitions. Using 6895 causes minor errors in calculations, usually insignificant for everyday use.
How does temperature affect the psi to pa conversion?
The conversion factor itself does not change with temperature since it’s a unit conversion. But actual pressure values in psi or pa can change if measured under different temperatures due to gas expansion or contraction affecting pressure readings.
