PSI Conversion Formula:
From: | To: |
Definition: This calculator converts pounds per square inch (lb/in²) to pounds per square inch (PSI), which are equivalent units of pressure.
Purpose: It provides a simple way to verify pressure calculations or convert between these identical but differently expressed units.
The calculator uses the formula:
Where:
Explanation: PSI is calculated by dividing the force (pounds) by the area (square inches) over which the force is distributed.
Details: Accurate pressure calculations are essential in engineering, hydraulics, pneumatics, and many industrial applications where force distribution matters.
Tips: Enter the force in pounds and the area in square inches. Both values must be greater than 0.
Q1: Are lb/in² and PSI the same thing?
A: Yes, they are identical units of pressure. 1 lb/in² = 1 PSI.
Q2: Why have two names for the same unit?
A: PSI is the more common term, while lb/in² explicitly shows the unit components (pounds divided by square inches).
Q3: What are typical PSI values in everyday applications?
A: Car tires (30-35 PSI), bicycle tires (40-65 PSI), scuba tanks (3000 PSI), hydraulic systems (1000-5000 PSI).
Q4: How precise should my measurements be?
A: For most applications, 1-2 decimal places is sufficient. High-pressure systems may require more precision.
Q5: Can I use this for metric units?
A: No, this is specifically for imperial units. For metric, you'd use Pascals (N/m²) or bars.
