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).

Frequently Asked Questions

There are exactly 689475.72931684 dekapascals (daPa) in 1 kilopound/sq. inch (ksi). To calculate larger amounts manually, simply multiply your total number of kilopounds/sq. inch by the conversion multiplier of 689475.72931684.

The mathematical formula to convert kilopounds/sq. inch to dekapascals is: [value] * 689475.72931684 = dekapascals. 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 dekapascals back to kilopounds/sq. inch, you must divide your starting value by 689475.72931684. Our bidirectional tool automatically computes this inverse equation the moment you type into the dekapascal input field.

1 Kilopound/sq. inch is larger than 1 Dekapascal. Specifically, 1 Kilopound/sq. inch equals exactly 689475.72931684 dekapascals, making it 689475.7293 times larger (a difference of 5.84 orders of magnitude). Therefore, quantities expressed in dekapascals require a larger numerical value to represent the same physical amount.

A typical structural steel ASTM A36 minimum tensile yield strength limit measures 36 ksi, which corresponds to 2.4821 × 10⁷ Dekapascal (Dekapascal).

There are exactly 6.89476 × 10⁵ daPa in a single Kilopound/sq. inch. The exact conversion is expressed as 1 ksi = 6.89476 × 10⁵ daPa.

To yield Dekapascal, multiply the ksi value by 6.89476 × 10⁵. The structural equation is V(daPa) = V(ksi) × 6.89476 × 10⁵.

Reverse the conversion by multiplying the Dekapascal value by 1.45038 × 10⁻⁶. The corresponding formula is V(ksi) = V(daPa) × 1.45038 × 10⁻⁶.

While Dekapascal is rarely used in high-pressure heavy engineering (where ksi dominates), 1 daPa equals 10 Pa, serving as a micro-pressure differential metric in HVAC systems.
