Nm to Psi Calculator

Formula

The formula to convert torque (Nm) to pressure (Psi) is:

\[ \text{Psi} = \frac{\text{Torque} \times 8.85074579}{\pi \times \text{Radius}^2} \]

Where:

\(\text{Psi}\) is the pressure in pounds per square inch
\(\text{Torque}\) is the force in Newton-meters
\(\text{Radius}\) is the distance from the center of rotation to the point of force application in inches

What is Torque?

Torque is a measure of the force that can cause an object to rotate about an axis. It is a vector quantity, meaning it has both magnitude and direction. Torque is typically measured in Newton-meters (Nm) in the metric system or foot-pounds (ft-lbs) in the imperial system.

What is Psi?

Psi stands for pounds per square inch and is a unit of pressure commonly used in the United States. It measures the amount of force applied over a one square inch area.

Example Calculation 1

Let's assume the following values:

Torque = 50 Nm
Radius = 2 inches

Using the formula:

\[ \text{Psi} = \frac{50 \times 8.85074579}{\pi \times 2^2} = 35.22 \text{ Psi} \]

The Pressure is 35.22 Psi.

Example Calculation 2

Let's assume the following values:

Torque = 100 Nm
Radius = 3 inches

Using the formula:

\[ \text{Psi} = \frac{100 \times 8.85074579}{\pi \times 3^2} = 31.29 \text{ Psi} \]

The Pressure is 31.29 Psi.
