# RPM to Ft/min Calculator Online

The RPM to Ft Min Calculator is designed to convert the speed of a rotating object, measured in revolutions per minute (RPM), into its corresponding linear velocity in feet per minute (FPM). This tool is particularly useful in mechanical engineering, automotive, and manufacturing industries, where precise calculations are necessary for optimizing performance and safety.

### Formula of RPM to Ft/min Calculator

The fundamental formula used by the RPM to Ft Min Calculator is:

FPM = RPM * Diameter * π

Where:

• FPM is the linear velocity in feet per minute.
• RPM is the rotational speed in revolutions per minute.
• Diameter is the diameter of the wheel or rotor in feet.
• π (pi) is the mathematical constant, approximately 3.14159.

### Useful Conversion Table

For ease of use, here is a table with pre-calculated values that can help users apply the calculator without performing calculations every time:

This table serves as a quick reference for commonly encountered situations, simplifying the process and enhancing efficiency.

### Example of RPM to Ft/min Calculator

Consider a scenario where you need to find the linear velocity of a car tire with a diameter of 2 feet, rotating at 100 RPM. Using the formula:

FPM = 100 * 2 * π = 628.318 feet per minute

This example illustrates how to use the calculator to determine the speed at which the tire travels in a minute.
