Convert kilopascals to pounds per square inch at the rate 1 kPa ≈ 0.1450 psi. Common contexts: 200 kPa = 29.0 psi (typical car tire), 300 kPa = 43.5 psi (motorcycle tire), 700 kPa = 101.5 psi (high-pressure bike tire). Useful when metric automotive or industrial specs need to be expressed in US psi. Browser-local conversion.

Glossary

Kilopascal (kPa)

A kilopascal equals 1,000 pascals. It is the everyday metric pressure unit for tire pressure outside the US (32 psi ≈ 220 kPa), atmospheric pressure (~101 kPa at sea level), HVAC duct pressure and blood-pressure readings reported in metric form (120/80 mmHg ≈ 16.0/10.7 kPa). The standard atmosphere equals 101.325 kPa exactly.

Pound per square inch (psi)

A pound-force per square inch equals 6,894.76 Pa. It is the dominant pressure unit in US automotive and engineering: tire pressure (32 psi = 2.21 bar), hydraulic systems (1,000–3,000 psi), bicycle tires (60–120 psi), municipal water (60 psi typical). Standard atmospheric pressure is 14.696 psi. The unit is sometimes split as psi-g (gauge, above atmospheric) and psi-a (absolute).

Metric / SI pressure

In the metric system, pressure is reported in pascals (SI base) or its multiples — kilopascal (kPa, 10³ Pa), megapascal (MPa, 10⁶ Pa) — and the related non-SI unit bar (10⁵ Pa). The millibar/hectopascal (mbar = hPa = 100 Pa) is used in meteorology. All metric units relate by exact powers of ten, so conversions between them are simple shifts of decimal point.

Imperial / US pressure

US engineering and automotive primarily report pressure in pounds per square inch (psi). 1 psi ≈ 6,894.76 Pa, defined as one pound-force per square inch. Standard atmospheric pressure is 14.696 psi. The closely related "psi-gauge" (psi-g) measures pressure above atmospheric, while "psi-absolute" (psi-a) measures total pressure including atmospheric.
