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 Hectometer to Square Nanometer

Converting Square Hectometer (hm²) 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 (10^22). 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 Hectometer equals 1 × 10²² Square Nanometer.

1 Square Hectometer is larger than 1 Square Nanometer. Specifically, 1 Square Hectometer equals exactly 1 × 10²² square nanometers, making it 1 × 10²² times larger (a difference of 22.00 orders of magnitude). Therefore, quantities expressed in square nanometers require a larger numerical value to represent the same physical amount.

A typical metric agricultural land survey hectare equivalent parcel (100x100 m) measures 1 hm², which corresponds to 1 × 10²² Square Nanometer (Square Nanometer).
