Enter a gauge reading in PSI, kPa, or bar and get the other two instantly. That is the conversion you need when a placard is in kPa, a compressor is in PSI, and a European spec sheet is in bar — without a phone-calculator chain of factors.
The workspace uses standard SI conversions (PSI ↔ kPa ↔ bar), not “14.5 PSI ≈ 1 bar” napkin math. Results are rounded for a gauge (PSI/kPa to one decimal, bar to three) so you can set a shop inflator without fake precision.
You do not fill three boxes. Change the unit and the value; the other two update live. Inputs that exceed about 1000 kPa equivalent are rejected so a typo does not look like a valid 200 PSI passenger-car setting on the gauge.
No account and no upload. Placard numbers and shop readings stay in the tab. This is a unit converter, not a recommended-pressure calculator — always follow the door sticker for daily cold PSI, not a forum number. Nothing is stored on a server.
Type the number from the placard, the gauge, or the spec sheet. Use a comma or a dot for decimals.
Match the unit of the number you typed. The other two units fill in automatically.
Use the unit your inflator or TPMS app expects. Rounding is gauge-friendly, not laboratory digits.
Conversion does not choose a target PSI. Inflate to the door-jamb spec, measured cold, unless a manufacturer procedure says otherwise.
