Convert a tire or gauge pressure
The pump reads bar, the door sticker says psi, the manual is in kPa — translate between them.

The job
Pressure units collide at the gas station and the workshop. A tire spec of 240 kPa is 34.8 psi; a hydraulic gauge at 200 bar is about 2,900 psi — knowing one in the other's units prevents expensive mistakes.
Value plus unit
Enter a number in psi, bar, kPa, MPa, atm, mmHg, inHg, or Pa and read all eight at once. Handy both for 'psi to bar' and for reading a foreign spec sheet.
Worked example
32 psi = 2.21 bar = 220.6 kPa. Standard atmospheric pressure is 14.696 psi = 1.013 bar = 760 mmHg = 29.92 inHg — a useful sanity check.
Where it stops
The number converts as-is; gauge vs absolute is your responsibility (a tire '30 psi' is already gauge). Negative inputs are refused — vacuum ratings are written positive in practice anyway.
