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 metre (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 the US and UK for tyre pressure, gas pressure, etc.
  • Atmosphere (atm): Approximately equal to Earth's atmospheric pressure at sea level
  • mmHg (Millimetres 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)
