Convert kilopascals to pascals using the SI relation 1 kPa = 1,000 Pa. Anchors: 1 kPa = 1,000 Pa, 100 kPa = 100,000 Pa, 101.325 kPa = 101,325 Pa (sea-level atm). Useful when kPa-level instrument readings need to feed into a physics calculation that expects raw pascals. 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.

Pascal (Pa)

The pascal is the SI derived unit of pressure, defined as one newton per square meter (1 Pa = 1 N/m²). Named after Blaise Pascal. The Pa is too small for most everyday quantities — atmospheric pressure is about 101,325 Pa — so kilopascals (kPa) and megapascals (MPa) are used in practice. Common in fine-resolution scientific and engineering calculations.

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.
