Frequently Asked Questions
-
What does one pound-force per square inch represent?
-
It is an imperial pressure unit defined as one pound-force applied over one square inch of area.
-
Is newton per square meter the same as a pascal?
-
Yes, one newton per square meter equals one pascal (Pa), the SI unit of pressure.
