Frequently Asked Questions
Which pressure units are supported?
Our converter supports all major pressure units including Pascal (Pa), Bar, PSI, Atmosphere, mmHg, Torr, and more. Perfect for engineering, automotive, and scientific applications.
What's the difference between gauge and absolute pressure?
Gauge pressure measures relative to atmospheric pressure, while absolute pressure includes atmospheric pressure. Our converter uses absolute pressure for consistency across all units.
How accurate are pressure conversions for automotive use?
Extremely accurate! Perfect for converting tire pressure between PSI, Bar, and kPa. Our conversions match automotive industry standards for precision.
Can I use this for vacuum measurements?
Yes! The converter supports units commonly used in vacuum applications like Torr, mmHg, and micron. Perfect for laboratory and industrial vacuum systems.
What's standard atmospheric pressure?
Standard atmospheric pressure is 1 atmosphere = 101.325 kPa = 1.01325 bar = 14.696 PSI = 760 mmHg. This is used as a reference in many engineering calculations.
Is this suitable for HVAC calculations?
Absolutely! Perfect for HVAC system pressure calculations, converting between inches of mercury, PSI, and pascals for air handling and refrigeration systems.
