Real-World Pressure Conversions

🚗

Tire Pressure

Car tires are typically inflated to 30-35 PSI (2.0-2.4 bar). Proper tire pressure improves fuel efficiency and safety. Converting between PSI, bar, and kPa for international vehicles.

🌤️

Weather and Meteorology

Barometric pressure is measured in millibars (mb) or hectopascals (hPa). Standard pressure is 1013.25 mb. High pressure (>1020 mb) brings clear weather, low pressure (<1000 mb) brings storms.

🤿

Scuba Diving

Underwater pressure increases by 1 atmosphere (14.7 PSI) every 33 feet of depth. Dive computers and tanks use bar or PSI. Understanding pressure is critical for diver safety.

❄️

HVAC and Refrigeration

Air conditioning systems use PSI or bar for refrigerant pressure. Proper pressure ensures efficient cooling. Low pressure indicates leaks, high pressure suggests system problems.

🏥

Medical Applications

Blood pressure is measured in mmHg (millimeters of mercury). Normal blood pressure is around 120/80 mmHg. Medical gas cylinders also use PSI or bar.

🏭

Industrial Processes

Manufacturing uses various pressure units for hydraulics (PSI), pneumatics (bar), and vacuum systems (torr or Pa). Accurate pressure control ensures product quality.
