1. What is Pressure?

Definition: Pressure is the ratio of force per unit area (P = F/A).

Purpose: This calculator helps determine the pressure exerted when a force is applied over a specific area.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Pressure (Pascals)
• \( F \) — Force (Newtons)
• \( A \) — Area (square meters)

Explanation: The force is divided by the area over which it's distributed to calculate pressure.

3. Importance of Pressure Calculation

Details: Pressure calculations are crucial in engineering, physics, and many practical applications like hydraulic systems, structural design, and fluid mechanics.

4. Using the Calculator

Tips: Enter the force in Newtons and area in square meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are the units of pressure?
A: The SI unit is Pascal (Pa), which equals 1 N/m². Other common units include psi, bar, and atm.

Q2: How does area affect pressure?
A: For a given force, pressure increases as area decreases (sharper objects exert more pressure).

Q3: What's a typical pressure example?
A: Atmospheric pressure at sea level is about 101,325 Pa (101.325 kPa).

Q4: Can I use different units?
A: The calculator uses SI units. Convert other units to N and m² before calculation.

Q5: What if my area is in cm²?
A: Convert cm² to m² by dividing by 10,000 (since 1 m² = 10,000 cm²).
