Q1. Which unit should I check tire pressure in?

Vehicle manuals usually show psi or bar. Pick psi as the source and bar as the target to convert instantly (1 bar ≈ 14.5 psi).

Q2. How many Pascals is one atmosphere?

Standard atmospheric pressure, 1 atm, equals 101,325 Pa (about 101.325 kPa).

Q3. Are mmHg and torr the same unit?

Practically yes. One torr is nearly identical to one mmHg (133.322 Pa), commonly used for blood pressure or vacuum gauges.

Q4. How many decimal places are shown?

Results are shown with up to 6 decimal places. Very small discrepancies can come from rounding.

Q5. Is my input sent to a server?

No. All calculations happen entirely in your browser and are never sent to or stored on a server.
