- RPM measures how many times an object rotates per minute.
- FPM describes the linear speed an object moves over a distance.
Converting RPM to FPM ensures accurate performance and operational efficiency in various mechanical and industrial systems.
How to Use the RPM to Feet per Minute Calculator
Our calculator simplifies the process by supporting various units for both speed and diameter:
• Speed: Input in RPM or radians per second (Rad/s).
• Diameter: Input in inches (in), feet (ft), or meters (m).
Follow these steps to calculate FPM:
1. Select the speed unit (RPM or Rad/s) and input the value.
2. Choose the diameter unit (inches, feet, or meters) and input the value.
3. Click “Calculate” to get the linear speed in Feet per Minute.
You can also perform reverse calculations using our Feet per Minute to RPM Calculator.
How to Convert RPM to Feet per Minute
To calculate FPM from RPM, you need to know the circumference of the rotating object, which depends on its diameter. Follow these steps:
- Calculate the Circumference of the Rotating Object
Use the formula:
Ensure the diameter is in feet for consistent units. Convert inches to feet if necessary.
- Convert RPM to FPM
Multiply the RPM by the circumference:
Example Calculation
Example 1: 1500 RPM with a Diameter of 24 inches
- Rotational Speed: 1500 RPM
- Diameter: 24 inches
- Convert the diameter to feet:
- Calculate the circumference:
- Convert RPM to FPM:
At 1500 RPM, the object travels 9,424.77 feet per minute.
Example 2: 500 Rad/s with a Diameter of 0.5 meters
Step 1: Convert Diameter to Feet
Step 2: Convert Rad/s to RPM
Step 3: Calculate Circumference
Step 4: Convert RPM to FPM
At 500 Rad/s, the object travels 24,606.31 feet per minute.
FAQs
Q: How do I convert Radians per Second (Rad/s) to RPM?
A: To convert Rad/s to RPM, use the formula: • RPM = (Rad/s × 60) / (2π) • This converts angular velocity from radians per second to revolutions per minute.
Q: Can I input the diameter in units other than feet?
A: Yes, our calculator accepts diameters in inches, feet, or meters. It automatically converts these measurements to feet for accurate FPM calculations.
Q: What is the relationship between linear speed (FPM) and angular speed (RPM or Rad/s)?
A: Linear speed (FPM) is directly proportional to angular speed. Increasing the rotational speed (RPM or Rad/s) or the diameter of the rotating object will result in a higher linear speed.
Q: How accurate are the calculations provided by the calculator?
A: The calculator uses precise mathematical formulas to ensure accurate conversions. However, for critical applications, it’s advisable to verify calculations independently.
Q: Can this calculator be used for belt and pulley systems?
A: Yes, understanding the linear speed in belt and pulley systems is essential for determining the belt’s speed and ensuring efficient power transmission.
