PSI Calculation Formula:
From: | To: |
Definition: This calculator converts force in pounds (lbs) to pressure in pounds per square inch (PSI) based on the contact area.
Purpose: It helps engineers, mechanics, and DIYers determine pressure exerted when a force is applied over a specific area.
The calculator uses the formula:
Where:
Explanation: The force in pounds is divided by the area in square inches to calculate the pressure in PSI.
Details: Proper pressure calculation ensures safe operation of hydraulic systems, proper tire inflation, and structural integrity in construction.
Tips: Enter the force in pounds and the contact area in square inches. Both values must be > 0.
Q1: What is PSI used for?
A: PSI measures pressure in various applications including tire pressure, hydraulic systems, and material strength testing.
Q2: How do I measure the area?
A: For regular shapes use geometry formulas. For irregular shapes, approximate or use specialized measurement tools.
Q3: What's the difference between PSI and PSIG?
A: PSI measures absolute pressure, while PSIG measures pressure relative to atmospheric pressure.
Q4: Can I use this for hydraulic calculations?
A: Yes, this is fundamental for hydraulic system pressure calculations.
Q5: What's a typical PSI range for car tires?
A: Most passenger car tires require 30-35 PSI, but always check your vehicle's specifications.
