Instantly convert between Bar, Pascal, PSI, and Atmosphere. Essential for automotive, meteorology, engineering, and physics calculations.
Pressure is defined as the force exerted per unit area. It is a critical parameter in thermodynamics, fluid mechanics, and meteorology. Different regions and industries rely on different units to measure it.
1 Bar ≈ 14.5038 PSI. This is the most frequent conversion for checking tire pressure on European vs US cars.
1 atm = 101,325 Pa (or 101.325 kPa). This is the standard reference for weather reports and chemistry.
From Tires to Weather.
Car manuals often list tire pressure in Bar (e.g., 2.2 bar), but many air pumps at gas stations gauge in PSI. Use this tool to quickly find the correct PSI setting (approx 32 psi) for safety and fuel efficiency.
Ensure optimal pressure.
Torr is a unit of pressure based on the absolute scale, exactly 1/760 of a standard atmosphere. It is historically related to millimeters of mercury (mmHg).
Very close, but not exactly. 1 Bar = 0.986923 Atmospheres. For rough estimations, they are often treated as interchangeable, but scientific calculations require precision.
