Convert Bars to Kilopascals
Convert Bars (bar) to Kilopascals (kPa) instantly and accurately.
Conversion Formula
kPa = bar × 100
About Bars
A bar = exactly 100,000 Pa ≈ 0.987 atm - the world standard for industrial pressure outside North America. Hydraulic systems, pneumatic equipment, gas cylinders, dive computers, and tyre gauges in Europe and Asia use bar. Scuba diving: +1 bar per 10 m depth; at 40 m recreational limit = 5 bar absolute. European tyre pressure labels show bar alongside kPa. Industrial processes: steam at 10-50 bar; high-pressure reactors 100-300 bar; water-jet cutting 1,000-4,000 bar. 1 bar = 100,000 Pa = 14.504 psi.
About Kilopascals
A kilopascal (kPa) = 1,000 Pa - the practical everyday SI pressure unit for moderate pressures. Car tyre inflation: 200-250 kPa (29-36 psi); truck tyres 550-830 kPa. Blood pressure in SI countries: 16/10.7 kPa (= 120/80 mmHg). Systolic blood pressure 16 kPa. Carbonated beverages are packaged at 200-500 kPa CO₂. Medical oxygen cylinders at 15,000 kPa; scuba cylinders 200-300 bar = 20,000-30,000 kPa. 1 kPa = 1,000 Pa = 0.01 bar = 0.145 psi.
