About this tool
Pressure is force per area. All values pass through the pascal (N/m²). One atmosphere is defined as 101,325 Pa.
How it works
Enter a pressure, pick units, and read the converted value. Negative values are rejected.
value_to = value_from × (from_in_pascals / to_in_pascals)
Examples
1 atm to psi
101,325 / 6,894.757 ≈ 14.696 psi.
FAQ
Is mmHg the same as torr?
They are treated as equal here (1 mmHg = 133.322 Pa).
Gauge or absolute?
This tool converts unit scales only. It does not add or subtract atmospheric pressure.
