Pressure Converter
Convert pascals, bars, atmospheres, PSI, and mmHg. Used in tire inflation, weather systems, scuba diving, and industrial engineering.
Formula
target = source × (sourceToBase / targetToBase)
Pressure is normalized to pascals (Pa). One pascal equals one newton per square meter. Other units like PSI and bar use defined conversion factors to pascals.
Example
- Convert: 1 m × 3.28084= 3.28 ft
Result: 1 meter = 3.28 feet
Frequently Asked Questions
What PSI should car tires be inflated to?
Most passenger cars recommend 30–35 PSI, but always check the sticker on your driver's door jamb or the owner's manual for the exact specification.
How do I convert bar to PSI?
Multiply bar by 14.5038. One bar equals approximately 14.5 PSI and is roughly equal to atmospheric pressure at sea level.
What is mmHg used for?
Millimeters of mercury (mmHg) is used in blood pressure readings and vacuum measurements. Normal blood pressure is around 120/80 mmHg.
