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 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: Understanding pressure is crucial in engineering, physics, and many practical applications like hydraulic systems, structural design, and fluid mechanics.
Tips: Enter the force in Newtons and area in square meters. Both values must be greater than 0.
Q1: What are the units of pressure?
A: The SI unit is Pascal (Pa), which equals 1 Newton per square meter. Other common units include psi, bar, and atm.
Q2: How does area affect pressure?
A: For a constant force, pressure increases as area decreases (sharp knives cut better because force is concentrated on a small area).
Q3: What's a typical pressure example?
A: Atmospheric pressure at sea level is about 101,325 Pa (101.325 kPa).
Q4: Can pressure be negative?
A: In physics, pressure is typically positive, but gauge pressure can be negative relative to atmospheric pressure.
Q5: How do I convert between pressure units?
A: Use our Unit Converter tool or remember that 1 psi ≈ 6894.76 Pa and 1 bar = 100,000 Pa.
