About Pressure Units

Pressure units are used in various scientific, engineering, and everyday applications, from weather forecasting to industrial processes.

Common Pressure Units
  • Pascal (Pa): The SI unit of pressure, equal to one newton per square meter (N/m²)
  • Kilopascal (kPa): 1,000 pascals, commonly used in meteorology
  • Bar: Approximately equal to atmospheric pressure at sea level, used in many applications
  • PSI (Pounds per Square Inch): Common in US and UK for tire pressure, gas pressure, etc.
  • Atmosphere (atm): Approximately equal to Earth's atmospheric pressure at sea level
  • mmHg (Millimeters of Mercury): Also known as Torr, often used in medicine and vacuum measurements
Practical Applications
  • Tire pressure (typically measured in PSI or Bar)
  • Blood pressure (typically measured in mmHg)
  • Weather forecasting (typically using hectopascals or millibars)
  • Industrial processes (using various units depending on the application)
  • Scuba diving (water pressure typically measured in bar)
Pressure Conversion Formulas:
  • 1 Kilopascal (kPa) = 1,000 Pascal (Pa)
  • 1 Bar = 100,000 Pascal (Pa)
  • 1 PSI = 6,894.76 Pascal (Pa)
  • 1 Atmosphere (atm) = 101,325 Pascal (Pa)
  • 1 mmHg (Torr) = 133.322 Pascal (Pa)

How to Use the Calculator

Using the calculator is straightforward and requires no technical skills. Follow these steps:

  • Enter a value into any of the available input fields (e.g., PSI or mmHg).
  • Click the “Convert” button to instantly see the equivalent values in all other units.
  • If needed, click the “Reset” button to clear all fields and start over.

The tool automatically calculates and displays the results, making quick unit conversions smooth and hassle-free.

Why Use This Pressure Conversion Tool?

This measurement converter is practical in many real-life situations. Here are just a few examples of where it can help:

  • Automotive: Check or convert tire pressure (often in PSI or Bar).
  • Medical: Understand blood pressure readings, typically shown in mmHg.
  • Meteorology: Convert weather data involving pressure units like kilopascals or millibars.
  • Engineering: Switch between pressure units for mechanical or hydraulic systems.
  • Scuba Diving: Gauge and convert underwater pressure (commonly in bars or atmospheres).

Conversion Reference Table

Here’s a quick reference for common pressure unit conversions:

  • 1 Bar = 14.5038 PSI
  • 1 Atmosphere = 760 mmHg
  • 1 Bar = 0.986923 Atmosphere
  • 1 kPa = 0.01 Bar
  • 1 PSI = 51.7149 mmHg

FAQ

Can I enter values in any unit?

Yes. Just type a number into the field for any pressure unit. The calculator will update the other units instantly.

Is this calculator suitable for scientific use?

Absolutely. The pressure values are converted using standard conversion factors, making this tool useful for both educational and professional purposes.

What happens if I input values into multiple fields?

The calculator is designed to respond to the most recent input. For accurate results, input your value into one field at a time.

Is this calculator the same as a general unit conversion tool?

It's specifically focused on pressure, but it's part of a wider range of tools like density formula tool, square footage to meters converters, and angle conversion tools such as those to convert degrees to radians.
