The process of converting 76 centimeters of mercury pressure into Newton per meter squared involves dimensional analysis. The calculation uses the density, acceleration due to gravity, and area dimensions. By substituting values like mass in kilograms (1 gram = 10^-3 kg) and length conversions (100 cm = 1 m), the result is expressed scientifically as approximately 1.012928 × 10^5 N/m².
