Frequently Asked Questions About Pressure Converter
How do I convert psi to bar?
Multiply the psi value by 0.0689476. For example, 30 psi equals about 2.07 bar. This tool does it instantly and shows every other unit too.
What is one atmosphere in psi?
One standard atmosphere (atm) equals about 14.6959 psi, or 101,325 pascals, or 1.01325 bar. It represents average air pressure at sea level.
What is the difference between mmHg and torr?
They are nearly identical — one torr is defined as 1/760 of a standard atmosphere, and one mmHg is almost exactly the same. For everyday conversions they are interchangeable.
Can I use this for tire pressure?
Yes. Converting between psi, bar, and kPa is exactly what you need for tire pressure, and this tool shows all three at once.
