Understanding the Units
What is a Pascal?
The pascal is the SI derived unit of pressure, equal to one newton of force per square meter (1 Pa = 1 N/m²).
Named after Blaise Pascal (1623–1662), the French mathematician and physicist whose experiments characterized atmospheric pressure.
Common contexts: fluid mechanics, meteorology.
What is a Pounds per Square Inch?
One pound-force per square inch (psi) equals approximately 6,894.757 pascals.
Common contexts: tire pressure, plumbing, pneumatic systems (US).
