Pressure
Choose conversion type
Convert between pressure units used in meteorology, engineering, automotive, and industrial settings. Pressure is force per unit area. The pascal (Pa) is the SI unit: one newton per square meter. Everyday units include bar (often used for tire and hydraulic pressures in Europe), pounds per square inch (psi) in the US, and atmospheres (atm) in chemistry and diving contexts. Weather reports may use hectopascals (1 hPa = 100 Pa), which equals one millibar. Tire gauges, HVAC specs, and lab equipment mix these units—our tool keeps factors exact: 1 atm = 101,325 Pa, 1 bar = 100,000 Pa, 1 psi ≈ 6894.76 Pa. Use this page to compare specs, interpret datasheets, or study—without sending data anywhere.
Supported units: pascal (Pa), bar, psi, atmosphere (atm).

Brief explanation: pascal to bar
Convert via pascals: multiply value by the unit’s Pa factor, then divide by the target’s factor. Standard atmosphere is 101,325 Pa.
