What is Pressure?

Pressure is force per unit area (P = F/A). It's measured in Pascals (Pa) and is fundamental in physics, engineering, meteorology, and medicine.

1 atmosphere (atm) = 101,325 Pa = pressure exerted by Earth's atmosphere at sea level.

Formula

P = F / A

Where:
- P = Pressure (Pascals)
- F = Force (Newtons)
- A = Area (m²)

Conversions:
1 atm = 101,325 Pa
1 bar = 100,000 Pa
1 psi = 6,894.76 Pa
1 mmHg = 133.322 Pa

How to use this Pressure Calculator?

1. Enter force in Newtons. 2. Enter area in square meters. 3. See pressure in Pa, kPa, atm, and psi.

Frequently asked questions

What is normal atmospheric pressure?
1 atm = 101,325 Pa = 1013.25 hPa. Weather reports use hectopascals (hPa) or millibars.
What is normal blood pressure in mmHg?
Normal blood pressure is 120/80 mmHg (systolic/diastolic). That's about 0.16 atm.
What is tire pressure measured in?
Tire pressure is typically measured in psi (pounds per square inch) or bar. Normal car tire: 30-35 psi or 2.0-2.4 bar.
