Pressure Calculator

Pressure is the force applied perpendicular to a surface per unit area. It is a measure of the force distributed over an area and is fundamental in many areas of physics and engineering.

Key concepts about pressure:

• Measured in Pascals (Pa) or N/m² in the International System of Units (SI)
• Represents the intensity of force acting on a surface
• Is a scalar quantity (has magnitude but no direction)
• Acts equally in all directions in a fluid at rest (Pascal's principle)

Common pressure units and conversions:

• 1 Pascal (Pa) = 1 N/m²
• 1 bar = 100,000 Pa
• 1 atmosphere (atm) = 101,325 Pa
• 1 pounds per square inch (psi) = 6,894.76 Pa

1. Enter the force in Newtons (N)
2. Enter the area in square meters (m²)
3. Click "Calculate" to see the results

The calculator will display:

• Pressure in Pascals (Pa)
• The input force value
• The input area value

Note: The calculator assumes:

• The force is applied perpendicular to the surface
• The pressure is uniform over the entire area
• The system is in equilibrium

Pressure is calculated using the formula:

P = F/A

Where:

• P = Pressure (Pa or N/m²)
• F = Force (N)
• A = Area (m²)

This formula shows that:

• Pressure increases when force increases (direct relationship)
• Pressure decreases when area increases (inverse relationship)
• The same force applied to a smaller area creates higher pressure
• Doubling the force doubles the pressure (if area remains constant)
• Doubling the area halves the pressure (if force remains constant)

Pressure calculations are essential in many fields:
