Definition of Psi
PSI: Pound per Square Inch
PSI (pound-force per square inch or lbf/in²) is a unit of pressure commonly used in the United States and other countries that use imperial units. It measures the force in pounds applied to an area of one square inch. PSI is widely used for tire pressure, hydraulic systems, pneumatic tools, and various industrial applications.
Conversions to Other Units of Measurement:
- Bar: 1 psi equals approximately 0.0689476 bar. This conversion is essential for international equipment specifications. For example, 30 psi equals approximately 2.07 bar.
- Pascal (Pa): 1 psi equals approximately 6,894.76 pascals. This conversion connects imperial to SI units. For example, 14.7 psi (approximately 1 atm) equals about 101,325 Pa.
- Kilopascal (kPa): 1 psi equals approximately 6.89476 kPa. This is frequently used in automotive and engineering contexts. For example, a tire pressure of 32 psi equals approximately 220.6 kPa.
- Atmosphere (atm): 1 psi equals approximately 0.068046 atm. Standard atmospheric pressure (1 atm) equals approximately 14.696 psi.
- Kilogram-force per square centimeter (kgf/cm²): 1 psi equals approximately 0.070307 kgf/cm². This conversion is used in older metric equipment.
PSI remains the dominant pressure unit in North America for everyday applications like tire inflation, air compressors, and blood pressure (though medical uses mmHg).

About the Psi
Facts & Uses
- Pounds per square inch — the dominant pressure unit in US and UK engineering. 1 psi = 6894.757 Pa (derived from 1 lbf and 1 in², not exact in SI).
- Standard for US tire pressure (cars 30-35 psi, bicycles 60-100 psi), plumbing (40-80 psi household water), and compressed air tools.
- Common in gauge measurements: psig (gauge, relative to atmospheric) vs psia (absolute, including atmospheric pressure of 14.7 psi).
- Used in scuba diving in the US (3000 psi tanks), oil & gas industry, boiler ratings, and welding cylinders.
Curiosities
- 1 atm = 14.696 psi exactly — the value taught in US chemistry classes as the standard reference for sea-level pressure.
- The pressure inside a champagne bottle is 5-6 bar (75-90 psi) — about three times typical car tire pressure, which is why corks fly with such force.
- The deepest point in the Mariana Trench exerts about 16,000 psi (110 MPa) — over 1000 atmospheres.
- Approximate equivalents: 14.7 psi ≈ 1 atm ≈ 1.01 bar ≈ 101.3 kPa ≈ 760 mmHg.

Frequently Asked Questions
How many kips per square inch are in one psi?
One psi equals 0.001 kips per square inch. To convert, multiply the psi value by 0.001. For the reverse, divide the kip per square inch value by 0.001 (or multiply by 1000).
What is 100 psi in kips per square inch?
100 psi = 0.1 kips per square inch. This is one of the most commonly searched conversions for this pair.
Is the psi-to-kip per square inch conversion exact?
Yes. The factor 0.001 is exact by international definition, not an approximation. Any imprecision comes only from the original measurement, not the conversion.
