How do you calculate hydraulic cylinder force from pressure and bore?

Cylinder force (F in N) equals hydraulic pressure (P in Pascals) multiplied by the piston cross-sectional area (A = π × r² in m²): F = P × A. For a 100mm (0.1m) bore cylinder operating at 200 bar (20,000,000 Pa), force = 20,000,000 × (π × 0.05²) = 157,080 N ≈ 157.1 kN (35,314 lbf or 16.0 metric tons).

What is the formula to convert PSI to cylinder clamp force?

Force in pounds (lbf) = Pressure (PSI) × Area (square inches). A 4-inch bore cylinder has an area of π × 2² ≈ 12.57 in². At 3,000 PSI hydraulic pressure, force = 3,000 × 12.57 = 37,710 lbf (18.85 US tons).

How to Convert Square Dekameter to Square Nanometer

Converting Square Dekameter (dam²) to Square Nanometer (nm²) is a core calculation in Surface Area, which measures the two-dimensional extent of a surface, planar boundary, or land parcel. Both units reside within the International System of Units (SI) and share an identical physical dimension vector ([L²]), separated strictly by a decimal order-of-magnitude factor (10^20). Because this shift involves integer powers of 10, the conversion is mathematically exact and free from decimal rounding or irrational fractional loss. Exactly 1 Square Dekameter equals 1 × 10²⁰ Square Nanometer.
