Pressure Formula:
From: | To: |
Definition: This calculator computes pressure using the fundamental formula relating force and area.
Purpose: It helps engineers, physicists, and students determine pressure exerted when a force is applied over a specific area.
The calculator uses the formula:
Where:
Explanation: Pressure is calculated by dividing the applied force by the area over which the force is distributed.
Details: Understanding pressure is crucial in engineering, construction, fluid mechanics, and many physics applications. It determines structural integrity, hydraulic system performance, and material behavior under load.
Tips: Enter the force in Newtons and area in square meters. Both values must be positive numbers.
Q1: What are the standard units in this formula?
A: The SI units are Pascals (Pa) for pressure, Newtons (N) for force, and square meters (m²) for area.
Q2: How do I convert other units to these standard units?
A: 1 kPa = 1000 Pa, 1 kN = 1000 N, 1 cm² = 0.0001 m². Use appropriate conversion factors.
Q3: Can I calculate force or area if I know pressure?
A: Yes! The formula can be rearranged: \( F = P \times A \) or \( A = \frac{F}{P} \).
Q4: What's a typical pressure value in everyday situations?
A: Atmospheric pressure is about 101,325 Pa. Car tire pressure is typically 200-300 kPa.
Q5: Why does smaller area increase pressure?
A: With the same force, concentrating it over a smaller area increases pressure (like high heels on soft ground).
