← Back to all conversions

Pressure Converter

Easily convert between Pascals (Pa), Kilopascals (kPa), Bars, Atmospheres (atm), Pounds per Square Inch (psi), Millimeters of Mercury (mmHg), and Torr. Whether you're in engineering, meteorology, chemistry, or tire maintenance, this tool helps you get fast and accurate conversions.

Why Use It?

  • Ideal for lab experiments, weather forecasting, mechanical systems, and industrial applications.
  • Converts between metric (SI) and imperial pressure units.
  • Accurate to four decimal places.
  • Great for students, professionals, and hobbyists alike.

Popular Conversions

Supported Units

  • Pascals (Pa) - SI unit of pressure
  • Kilopascals (kPa) - 1,000 Pascals
  • Bar - Commonly used in weather, diving, and engines
  • Atmospheres (atm) - Based on Earth's average atmospheric pressure at sea level
  • Pounds per Square Inch (psi) - Common in the US, especially for tire and gas pressures
  • Millimeters of Mercury (mmHg) - Used in medical and scientific applications (e.g., blood pressure)
  • Torr - Equivalent to mmHg; used in vacuum measurements

Common Uses

  • Tire pressure checks and conversions
  • Converting scientific lab measurements
  • Weather data interpretation (e.g., barometric pressure)
  • Industrial systems involving hydraulics or pneumatics
  • HVAC and gas system design

Frequently Asked Questions

What is the standard atmospheric pressure?

Standard atmospheric pressure is defined as 101,325 Pascals, or 1 atm. This is equivalent to 760 mmHg, 14.696 psi, or 1.01325 bar.

Are mmHg and Torr the same?

Practically, yes. 1 Torr is defined as exactly 1/760 of an atmosphere, which makes it nearly equal to 1 mmHg. They are often used interchangeably in vacuum and medical measurements.

Why are there so many pressure units?

Pressure units evolved from different measurement systems (metric vs imperial), and different industries adopted specific units for convenience. For example, psi is common in the US, while Pascals and bars are widely used elsewhere.
