About Pressure Measurement
Pressure is the force applied perpendicular to a surface per unit area. It's a fundamental quantity in physics and engineering, measured in pascals (Pa) in the SI system. Pressure conversions are essential in meteorology, engineering, medicine, and many industrial applications.
Common Applications
- • Weather forecasting and barometric readings
- • HVAC system design and operation
- • Automotive tire pressure monitoring
- • Medical blood pressure measurements
- • Industrial hydraulic and pneumatic systems
- • Vacuum technology and process control
Unit Systems
- • SI: pascal (Pa), kilopascal (kPa)
- • Metric: bar, millibar, atmosphere
- • Imperial: psi, pounds per square inch
- • Medical: mmHg, torr
- • Weather: inHg, hectopascal (hPa)
Pressure Types
Absolute pressure is measured relative to a perfect vacuum, while gauge pressure is measured relative to atmospheric pressure. Most pressure gauges read gauge pressure. Atmospheric pressure at sea level is approximately 14.7 psi (101.3 kPa) absolute.
