Statics 1.16 - How to convert units of pressure - Explained*

The pascal (Pa) is actually a very small unit of pressure. To show this, convert 1 Pa = 1 N/m2 to lb/ft2. Atmosphere pressure at sea level is 14.7 lb/in2. How many pascals is this? Answer Converting 1 Pascal (Pa) to lb/ft² and Atmospheric Pressure to Pascals: 1. *Given:* 1 Pascal (Pa) = 1 N/m² Atmospheric pressure at sea level = 14.7 lb/in² 2. *Step 1: Convert 1 Pa to lb/ft²:* To convert from N/m² to lb/ft², we use the following conversion factors: 1 N = 0.224809 lb (Newton to pound-force) 1 m² = 10.7639 ft² (square meter to square feet) Therefore: 1 Pa = 1 N/m² = 0.224809 lb / 10.7639 ft² 1 Pa ≈ 0.0209 lb/ft² 3. *Step 2: Convert Atmospheric Pressure to Pascals:* Atmospheric pressure is 14.7 lb/in². To convert lb/in² to Pascals, we use the following conversions: 1 lb = 4.44822 N (pound-force to newton) 1 in² = 0.00064516 m² (square inch to square meter) Therefore: Atmospheric pressure in Pascals = 14.7 lb/in² * (4.44822 N/lb) / (0.00064516 m²/in²) Atmospheric pressure ≈ 101325 Pa (which is 1 atmosphere) 4. *Step 3: Final Results:* 1 Pa ≈ 0.0209 lb/ft² Atmospheric pressure at sea level ≈ 101325 Pa
