Pressure Converter translates between pressure units, pascals, kilopascals, bar, psi, atmospheres, and more, instantly and accurately, for everything from car tyres to weather, diving, and engineering.
A very common everyday use is tyre pressure: cars often specify it in bar or kPa while gauges read psi, and the handy relationship (1 bar ≈ 14.5 psi = 100 kPa) makes the conversion quick. The calculator gives the exact figure so you inflate correctly.
Understanding the units helps: the pascal is the SI base but tiny, so kPa and bar are used practically (1 bar = 100,000 Pa), an atmosphere is roughly sea-level air pressure (≈ 1.013 bar), and, a frequent point of confusion, hPa and mbar are identical, which is why weather reports use them interchangeably.
Conversion runs in your browser with nothing uploaded, using precise factors. Pair it with the other ToolsMonk unit converters for automotive, scientific, and everyday measurement reference.
For tyres: 1 bar ≈ 14.5 psi = 100 kPa, handy when your car lists bar but your gauge reads psi
hPa and mbar are identical units, no conversion needed between them
Use atm (≈ 1.013 bar) as the sea-level reference point
