Practical Use Cases for Pressure Calculator
Hydraulic Press & Automotive Brake Force Multiplication
Calculate amplified output piston forces ($F_2 = F_1 \times A_2 / A_1$) in hydraulic jack cylinders and vehicle disc brakes.
Scuba Diving & Subsea Hydrostatic Water Pressure (Bar / PSI)
Compute total ambient pressure at underwater depths (adding 1 atm for every 10 meters / 33 feet of saltwater depth).

Key Terminology & Definitions
Pascal ($Pa$)
The SI unit of pressure equal to one Newton of force applied uniformly perpendicular over an area of one square meter ($1\text{ Pa} = 1\text{ N/m}^2$).
Pascal's Principle
A principle stating that pressure applied to an enclosed static fluid is transmitted undiminished to every portion of the fluid and container walls.
