Pressure Formula:
From: | To: |
Definition: This calculator converts force in pounds (lbf) to pressure in pounds per square inch (psi) using the area in square inches.
Purpose: It helps engineers, mechanics, and technicians calculate pressure from force and area measurements.
The calculator uses the formula:
Where:
Explanation: Pressure equals force divided by the area over which the force is distributed.
Details: Accurate pressure calculations are critical in hydraulic systems, pneumatic systems, structural engineering, and many mechanical applications.
Tips: Enter the force in pounds (lbf) and area in square inches (in²). Both values must be greater than zero.
Q1: What is the difference between psi and lbf?
A: PSI (pounds per square inch) is a unit of pressure, while lbf (pounds-force) is a unit of force.
Q2: How do I measure the area for this calculation?
A: Measure the contact area in square inches where the force is being applied.
Q3: What's a typical psi value for hydraulic systems?
A: Most hydraulic systems operate between 1,000-3,000 psi, but this varies by application.
Q4: Can I use this for tire pressure calculations?
A: Yes, if you know the weight supported by the tire and its contact patch area.
Q5: What if my area is in other units?
A: Convert to square inches first (1 in² = 6.4516 cm², 1 in² = 0.00694 ft²).
