Gas Spring Force Calculator

Gas springs are widely used in applications like automotive, industrial machinery, furniture, and aerospace. These springs help in lifting, lowering, and supporting loads with ease. If you're looking for an easy way to calculate the force exerted by a gas spring, our Gas Spring Force Calculator simplifies the process.

With this calculator, you can determine the required force based on the internal pressure and piston diameter. Whether you're working with metric units or need results in pounds-force (lbf), our tool provides instant and accurate calculations.

What is Gas Spring Force?

Gas springs work by compressing nitrogen gas within a sealed cylinder. The force exerted by the gas spring depends on two key factors:

1. Pressure (P) – The internal gas pressure, usually measured in Pascals (Pa), Kilopascals (kPa), Megapascals (MPa), Bar, or PSI (Pounds per Square Inch).
2. Piston Diameter (d) – The diameter of the piston that pushes against the gas, typically measured in millimeters (mm), centimeters (cm), meters (m), or inches (in).

By calculating the piston area (A) and multiplying it by the internal pressure (P), we determine the force exerted by the gas spring.

Gas Spring Force Calculation Formula

To calculate gas spring force, use the formula:

F = P × π × (d²) / 4

Where:

• F = Force exerted by the gas spring (Newtons)
• P = Internal gas pressure (Pascals)
• d = Piston diameter (meters)
• π = 3.14159 (Mathematical constant)

Example Calculation

Let's assume:

• Pressure (P) = 2 MPa (2,000,000 Pa)
• Piston Diameter (d) = 50 mm (0.05 m)

Step 1: Convert diameter to meters

d = 50 mm = 0.05 m

Step 2: Calculate piston area

A = π × (d²) / 4

A = 3.14159 × (0.05²) / 4

A = 3.14159 × 0.0025 / 4

A = 0.0019635 m²

Step 3: Calculate force

F = P × A

F = 2,000,000 × 0.0019635

F = 3927 N

Thus, the gas spring exerts a force of 3927 Newtons (N).
