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.
