Questions people ask
How do I convert pound per square inchs to bars?
Multiply by 0.0689475729. For example 10 psi = 0.68947573 bar.
What is the base unit for pressure?
The converter uses the pascal as its internal base. Every unit is converted to pascals and then to the target unit, so any pair of units works.
Where do the conversion factors come from?
From the legal definitions published in NIST Special Publication 811 and the SI Brochure (BIPM). Where a unit is defined exactly, the factor is exact.
