Formula to Convert RPM to m/s
The conversion from angular speed (RPM) to linear speed (m/s) relies on the circumference of the rotation path. Use this standard physics formula:
Where π (pi) is approximately 3.1416. We divide by 60 to convert "per minute" to "per second".
Step-by-Step Example
Example: Convert 1200 RPM with a radius of 0.5 meters into m/s.
- Step 1: Write the formula
Speed = (2 × π × Radius × RPM) ÷ 60 - Step 2: Substitute values
Speed = (2 × 3.1416 × 0.5 × 1200) ÷ 60 - Step 3: Multiply values
Speed = (2 × 3.1416 × 0.5 × 1200) = 3769.92 - Step 4: Divide by 60
Speed = 3769.92 ÷ 60 = 62.83 m/s
Final Answer: 62.83 m/s

Frequently Asked Questions (FAQs)
To convert RPM to meters per second (m/s), you must know the radius or diameter of the rotating object. First, find the circumference in meters. Then, convert RPM to revolutions per second by dividing by 60. Finally, multiply the revolutions per second by the circumference to get the m/s speed.
The formula for linear velocity (v) from RPM is: v = (RPM × π × diameter) / 60, where the diameter is measured in meters. This calculation determines the exact speed at the outer edge of a spinning disc or wheel. It is essential for determining belt speeds in various industrial applications.
Converting RPM to m/s is crucial in engineering to determine the linear surface speed of rotating components. This is vital for selecting appropriate cutting speeds in machining, ensuring conveyor belts move at the correct rate, and verifying that grinding wheels do not exceed safe velocity limits.
Yes, the radius directly and proportionally affects the meters per second speed. For a constant RPM, doubling the radius of the rotating object exactly doubles its linear velocity at the edge. The further a point is from the center of rotation, the faster it must travel to complete a revolution.
To find surface speed of a wheel, measure its diameter in meters and multiply by Pi to find the circumference. Then, multiply this circumference by the rotational speed in RPM, and divide the final result by 60 to obtain the accurate and precise surface velocity measured in meters per second.
