The Pressure Conversion Calculator is a practical utility tool designed to convert values between different units of pressure — such as Pascal, bar, psi, atm, and more — in real time. Whether you're a science student learning about physical forces, a weather enthusiast decoding barometric readings, or a mechanic working with tire pressure, this tool provides quick, accurate, and helpful conversions for everyday and professional use.
Pressure is defined as force per unit area, and it’s used in a wide range of fields — from meteorology and physics to aviation, plumbing, and car maintenance. But not all regions or industries use the same units. For example, meteorologists often use hectopascals (hPa), engineers in the U.S. might use psi (pounds per square inch), while scientists typically prefer the SI unit pascal (Pa).
This tool simplifies conversions between all common pressure units:
- Pascal (Pa) – SI unit (1 N/m²)
- Bar – Metric unit (100,000 Pa)
- Atmosphere (atm) – Standard atmospheric pressure (101,325 Pa)
- Pounds per square inch (psi) – Common in U.S. systems (~6,895 Pa)
- Hectopascal (hPa) – Used in meteorology (100 Pa)
- Torr or mmHg – Medical and laboratory settings (1 atm = 760 Torr)
Example:
Say your car tire pressure is listed as 2.24 atm. With this tool, you can instantly see that’s:
- 226,968 Pa
- 2.27 bar
- 32.87 psi
Just enter the known value, select the source and target units, and let the calculator do the rest — no need to remember the conversion factors.
Whether you’re checking aircraft cabin pressure, adjusting a bike tire, or converting laboratory data, this calculator is your go-to for fast, reliable answers.
