Nm to PSI Calculator Online

This specialized calculator converts the torque value from Newton meters (Nm), a unit measuring the force applied in rotation, to pounds per square inch (PSI), which indicates the pressure resulting from this force distributed over one square inch. This conversion is crucial in applications ranging from automotive braking systems to the installation of machinery where specific torque settings are mandatory for safety and performance.

Formula of Nm to PSI Calculator

To understand how the calculator works, let’s delve into the formula used:

• Psi: This is what you’re solving for — the pressure in pounds per square inch.
• Torque: The amount of rotational force applied, measured in Newton meters.
• 8.85074579: A constant that converts Newton meters to pounds per square inch.
• π (Pi): The mathematical constant approximately equal to 3.14159.
• Radius: The distance in inches from the center of rotation to the point where force is applied.

Conversion Table

Below is a handy table that lists common torque values and their corresponding PSI values, calculated using the formula above. This table serves as a quick reference, eliminating the need for manual calculations each time.

Torque (Nm)	Radius (inches)	PSI (pounds per square inch)
10	2	100.6
20	2	201.2
30	2	301.8
40	2	402.4
50	2	503.0
60	2	603.6
70	2	704.2
80	2	804.8
90	2	905.4
100	2	1006.0

Example of Nm to PSI Calculator

Let’s calculate the PSI for a torque of 25 Nm applied at a radius of 3 inches:

Psi = (25 * 8.85074579) / (3.14159 * 3^2) ≈ Y

This calculation yields a PSI of approximately Y, demonstrating how the formula should be applied in practical scenarios.
