1. What is Pressure to Torque Conversion?

Definition: This calculator converts pressure acting on a surface to torque (rotational force) based on the area and radius of application.

Purpose: It helps engineers and technicians determine the torque generated by fluid pressure in hydraulic systems, pneumatic systems, and other mechanical applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Torque (Newton-meters, Nm)
• \( P \) — Pressure (Pascals, Pa)
• \( A \) — Area (square meters, m²)
• \( r \) — Radius (meters, m)

Explanation: The pressure acting on an area creates a force, which when applied at a distance (radius) from the rotation axis produces torque.

3. Importance of Pressure-Torque Conversion

Details: Accurate torque calculation is essential for designing hydraulic motors, actuators, braking systems, and other rotational mechanisms.

4. Using the Calculator

Tips: Enter the pressure in Pascals, the effective area in square meters, and the radius in meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What are typical applications of this calculation?
A: Hydraulic motors, pneumatic actuators, torque wrenches, and braking systems often use this principle.

Q2: How does radius affect torque?
A: Torque increases linearly with radius - doubling the radius doubles the torque for the same force.

Q3: What units should I use?
A: The calculator uses SI units (Pa, m², m) for consistent Nm results. Convert other units first.

Q4: Does this account for efficiency losses?
A: No, this calculates theoretical torque. Real systems have friction and efficiency factors to consider.

Q5: Can I use this for angular torque calculations?
A: This is for linear force conversion. Angular torque calculations may require different formulas.
