14.7 psi equals 101325 pascals (pa).
This conversion comes from the relationship between pounds per square inch and pascals, where 1 psi is exactly equal to 6894.76 pa. Multiplying 14.7 psi by this factor gives the pressure in pascals, which is a metric unit for pressure measurement.

Conversion Formula
The formula to convert psi (pounds per square inch) to pascals (pa) is:
Pa = psi × 6894.76
This works because 1 psi equals 6894.76 pascals, which comes from the conversion of pounds-force per square inch into newtons per square meter (the SI unit for pressure). Pounds-force and newtons both measure force, but in different unit systems, so the conversion factor bridges imperial to metric units.
Example calculation for 14.7 psi:
- Start with 14.7 psi
- Multiply by 6894.76 pa/psi
- 14.7 × 6894.76 = 101325.972 pa
- Rounded result: 101325 pa
Conversion Example
- Convert 5 psi to pa:
- Multiply 5 × 6894.76 = 34473.8 pa
- Result: 34473.8 pa
- Convert 20 psi to pa:
- 20 × 6894.76 = 137895.2 pa
- Result: 137895.2 pa
- Convert 0.5 psi to pa:
- 0.5 × 6894.76 = 3447.38 pa
- Result: 3447.38 pa
- Convert 12.3 psi to pa:
- 12.3 × 6894.76 = 84779.548 pa
- Result: 84779.55 pa (rounded)
- Convert 7.8 psi to pa:
- 7.8 × 6894.76 = 53769.13 pa
- Result: 53769.13 pa

Conversion Definitions
psi: Psi stands for pounds per square inch, a unit of pressure measuring the force in pounds applied on one square inch of area. It is common in the United States for measuring tire pressure, hydraulics, and other engineering applications where imperial units prevail.
pa: Pascal (pa) is the SI unit of pressure equal to one newton per square meter. It quantifies force applied perpendicular to a surface area, used worldwide in scientific and engineering fields, offering a standard metric measurement for pressure.
Conversion FAQs
Can psi values be negative when converting to pascals?
Yes, negative psi indicates a pressure below atmospheric pressure or a vacuum. When converted to pascals, the value will also be negative, representing pressure less than zero relative to atmospheric pressure. This is useful in vacuum systems and suction calculations.
Why is 14.7 psi often linked with 101325 pascals?
Because 14.7 psi equals atmospheric pressure at sea level, which is standard atmospheric pressure measured as 101325 pascals. This relationship is used in many engineering and physics calculations involving air pressure and related phenomena.
Is the psi to pa conversion exact or approximate?
The conversion factor 6894.76 is exact based on defined units of force and area, so converting psi to pa using this factor will provide highly precise results, suitable for most scientific and engineering purposes without significant error.
How does temperature affect psi to pa conversion?
Temperature doesn’t directly change the conversion factor since psi and pa are units of pressure. But temperature changes can affect the pressure of gases, so measured psi or pa values may vary due to temperature changes, not the conversion itself.
Can I use the conversion formula for high-pressure values?
Yes, the formula is valid for any pressure value in psi, including very high pressures. The linear relationship between psi and pa remains true regardless of magnitude, but measurement accuracy depends on instruments rather than conversion.
