American tire gauges read in psi, but the tire's sidewall sometimes lists kilopascals too — 240 kPa next to 35 psi — and weather maps worldwide mark pressure systems in hectopascals, the kilopascal's close cousin. The kilopascal is the metric pressure unit engineers actually use: 1,000 pascals, where a pascal is one newton per square meter. Standard atmospheric pressure is 101.325 kPa. A car tire at 35 psi is about 241 kPa. Scuba tank pressures, HVAC refrigerant specs, and blood-pressure-adjacent medical devices all cross this unit.

Type your value in the Kilopascals (kPa) box and four translations appear: Pascals (Pa) at 1,000 each, Bar at 0.01 each, PSI (psi) at 0.1450377 each, and Atmospheres (atm) at 0.00986923 each. The 101.3 kPa example is the anchor — essentially one standard atmosphere, reading 1.0 atm on the nose. The psi column is the one American drivers need: divide kPa by 6.895 (or multiply by 0.145) to get the gauge reading. The bar column is nearly trivial — 100 kPa is exactly 1 bar — which is why European tire stickers favor it. Weather nerds note: meteorologists usually quote hectopascals, and 1 hPa is exactly 0.1 kPa, so 1013 hPa on the map is 101.3 kPa here.

With the pre-filled defaults — Kilopascals (kPa) 101.3 — the Kilopascal Converter returns Pascals (Pa) 101,300.0, Bar 1.013000, PSI (psi) 14.6923, Atmospheres (atm) 0.999753. Change any input and those results update instantly, so you can see exactly how each number you enter moves the answer.
