Every Pressure Unit Is the Pascal

The pascal (one newton per square meter) is the SI unit of pressure, and every other unit is a fixed multiple of it. That single fact makes conversion mechanical: multiply by the source unit's factor, divide by the target's, and the number is converted. This pressure converter applies those exact factors.

From Tire Gauges to Blood Pressure

psi on a tire gauge, kPa on a weather report, mmHg on a blood pressure monitor, atm on a dive table — the same physical quantity appears in dozens of guises. Having all of them at once is what this converter is for: pick any two units and see the full table alongside.

Exact Factors, No Rounding Drift

1 psi = 6,894.757293 Pa and 1 atm = 101,325 Pa exactly. Because the converter carries the base value in pascals and only rounds for display, converting 32 psi to kPa and back returns 32 psi — no accumulated rounding error.
