Pressure Formula:
From: | To: |
Definition: Pressure is the amount of force applied perpendicular to the surface of an object per unit area.
Purpose: This calculator helps determine the pressure exerted when a known force is applied over a specific area.
The calculator uses the formula:
Where:
Explanation: The force is divided by the area over which it's distributed to calculate the pressure.
Details: Pressure calculations are crucial in engineering, physics, and many practical applications like hydraulic systems, structural design, and fluid mechanics.
Tips: Enter the force in Newtons and the area in square meters. Both values must be positive numbers.
Q1: What is a Pascal (Pa)?
A: One Pascal is equal to one Newton per square meter (N/m²). It's the SI unit of pressure.
Q2: How do I convert to other pressure units?
A: 1 kPa = 1000 Pa, 1 bar ≈ 100,000 Pa, 1 psi ≈ 6895 Pa.
Q3: What's a typical pressure example?
A: Atmospheric pressure at sea level is about 101,325 Pa (101.325 kPa).
Q4: Why does area affect pressure?
A: The same force distributed over a larger area results in lower pressure (like snowshoes preventing sinking in snow).
Q5: Can pressure be negative?
A: In most physical systems, pressure is positive, but relative pressure can be negative compared to a reference.
