📘 Formula Sheet: Pressure Units & Conversions

🔢 Pressure Formula ▶

• Pressure (P) = Force (F) / Area (A)
• SI Unit of Pressure: Pascal (Pa) = 1 N/m²

🔄 Common Pressure Units ▶

• 1 Pascal (Pa) = 1 N/m²
• 1 kilopascal (kPa) = 1000 Pa
• 1 atmosphere (atm) = 101325 Pa
• 1 bar = 100000 Pa
• 1 mmHg ≈ 133.3 Pa
• 1 torr = 133.3 Pa
• 1 psi (pound/square inch) ≈ 6894.76 Pa

📏 Area Unit Conversions ▶

• 1 m² = 10,000 cm²
• 1 cm² = 100 mm²
• 1 m² = 1,000,000 mm²
• 1 inch² ≈ 645.16 mm²

🔧 Conversion Examples ▶

• Convert 2 atm to Pa: 2 × 101325 = 202650 Pa
• Convert 1 bar to N/m²: 1 × 100000 = 100000 N/m²
• Convert 10 psi to Pa: 10 × 6894.76 = 68947.6 Pa

🌊 Fluid Pressure Formulae ▶

• Pressure in fluids (P) = h × ρ × g
• h = height/depth of fluid column (in m)
• ρ = density of fluid (in kg/m³)
• g = gravitational acceleration (≈ 9.8 m/s²)

🌍 Atmospheric Pressure Facts ▶

• Standard Atmospheric Pressure = 101325 Pa = 1 atm
• Measured using a barometer
• Decreases with altitude
• Essential for weather forecasting and aviation
