Frequently Asked Questions

What is the formula for pressure from weight?

Pressure is defined as Force divided by Area ($P = F/A$). When dealing with weight, the formula becomes $P = W/A$. Since weight equals mass times gravity ($W = mg$), pressure can be calculated as $P = mg/A$.

How to convert PSI to weight?

PSI (Pounds per Square Inch) measures pressure, not weight. To find the total weight (force) exerted, you must multiply the PSI by the surface area in square inches. Formula: $Weight (Force) = PSI \times Area$.

What are the conversions for pressure?

Common benchmarks include: 1 Atmosphere (atm) = 14.7 PSI = 101,325 Pascals (Pa). 1 Bar = 14.5 PSI = 100,000 Pa. 1 PSI = 6,895 Pa.

What is the main purpose of a current to pressure converter?

An I/P (Current to Pressure) converter translates an electrical signal (usually 4-20 mA) into a pneumatic output (usually 3-15 PSI). This allows digital control systems to operate physical valves and dampers in industrial settings.

What are the three formulas of pressure?

1. General Pressure: $P = F/A$. 2. Hydrostatic Pressure (Fluids): $P = \rho g h$ (Density × Gravity × Height). 3. Ideal Gas Law: $P = nRT/V$.
