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 Are

Converting Square Dekameter (dam²) to Are (a) is a core calculation in Surface Area, which measures the two-dimensional extent of a surface, planar boundary, or land parcel. Both units share an identical 1:1 scale equivalence within this physical measurement domain. They represent the exact same physical magnitude under different metrological designations or derived SI formulations (1 dam² ≡ 1 a). Any quantity expressed in Square Dekameter translates directly to Are without mathematical scaling.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (square meter (m²)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 dam² = 100 square meter (m²)

2. Target SI Bridge (k_target):1 a = 100 square meter (m²)

Step-by-step substitution for Square Dekameter → Are:V(a) = V(dam²) × ( 100 / 100 ) = V(dam²) × 1

Mathematical FormulaValue in Are = Value in Square Dekameter × 1Direct computational formula applied for standard conversion.

Worked Example

To convert 50 Square Dekameter (dam²) to Are (a): multiply 50 by 1 to get 50 a. At an industrial engineering scale, 100 dam² converts to 100 a.
