Pressure Converter

Pressure conversion is essential in engineering, meteorology, medicine, automotive, and physics. Understanding different pressure units helps in tire pressure monitoring, weather forecasting, blood pressure readings, and industrial applications.

Common Pressure Units

• Pascal (Pa): SI unit of pressure (1 Pa = 1 N/m²)
• Kilopascal (kPa): 1,000 pascals
• Bar: Commonly used in meteorology (1 bar ≈ atmospheric pressure)
• PSI: Pounds per square inch (common in US for tire pressure)
• Atmosphere (atm): Standard atmospheric pressure at sea level
• mmHg: Millimeters of mercury (used in blood pressure)

Conversion Factors

• 1 PSI = 0.0689476 bar = 6.89476 kPa
• 1 atmosphere = 101,325 Pa = 101.325 kPa = 14.696 PSI
• 1 bar = 100,000 Pa = 100 kPa = 0.986923 atm
• 1 mmHg = 0.133322 kPa = 133.322 Pa

Applications

• Automotive: Tire pressure (typically 30-35 PSI or 2.0-2.4 bar)
• Weather Forecasting: Atmospheric pressure (millibars or kPa)
• Medical: Blood pressure (mmHg, e.g., 120/80 mmHg)
• HVAC: Air conditioning and heating system pressures
• Diving: Underwater pressure calculations (bar or atmospheres)
• Industrial: Hydraulic systems, compressors, pressure vessels
• Aviation: Cabin pressure, altimeter settings
