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).

The mathematical formula to convert square feet (us survey) to square meters is: [value] * 0.092903389 = square meters. Rather than doing the math manually, you can use our high-precision online calculator to process this exact equation instantly without rounding errors.

To perform the reverse calculation from square meters back to square feet (us survey), you must divide your starting value by 0.092903389. Our bidirectional tool automatically computes this inverse equation the moment you type into the square meter input field.

1 Square Meter is larger than 1 Square Foot (US survey). Specifically, 1 Square Foot (US survey) equals 0.092903389 square meters, meaning 1 Square Meter is 10.7639 times larger than 1 Square Foot (US survey) (a difference of 1.03 orders of magnitude). Expressing measurements in square feet (us survey) requires a larger numerical value to represent the equivalent physical magnitude.

A typical united States Coast and Geodetic Survey official legal boundary square foot measures 1 sq ft (US), which corresponds to 0.0929 m² (Square Meter).

By exact ISO 80000 metrological definition based on the US Survey foot standard (1 ft (US) = 12 / 39.37 m), 1 ft² (US) = 0.09290341161 m², commonly rounded to 1 ft² (US) = 0.0929034 m².

To convert an area from US survey square feet to square meters, multiply the value by the exact conversion factor 0.0929034: V(m²) = V(ft² (US)) × 0.0929034

To convert an area from square meters to US survey square feet, multiply the square meter value by 10.7639104 (or divide by 0.0929034): V(ft² (US)) = V(m²) × 10.7639

In state plane coordinate system (SPCS) land surveys, a typical residential lot measuring 10{,}000 ft² (US) equals exactly 929.034 m². The minor 2 ppm baseline difference between international and US survey feet scales to noticeable physical displacement across large geodetic tracts.
