This rpm to linear speed reference table shows the linear speed for a range of radius values, assuming a rotational speed of 1,000 RPM. Every figure is computed with the same engine that powers our RPM to Linear Speed Calculator, so the numbers are exact.
| Radius | Linear speed |
|---|---|
| 0.075 m | 7.8540 |
| 0.15 m | 15.7080 |
| 0.23 m | 24.0855 |
| 0.3 m | 31.4159 |
| 0.45 m | 47.1239 |
| 0.6 m | 62.8319 |
| 0.9 m | 94.2478 |
| 1.5 m | 157.0796 |
| 2.1 m | 219.9115 |
| 3 m | 314.1593 |
How to use this table
Find the row closest to your radius and read across to the linear speed. For a value between two rows, the real figure sits between them — or enter your exact numbers in the RPM to Linear Speed Calculator for a precise answer.
Need a value that is not in the table? — the RPM to Linear Speed Calculator does it instantly, for free, with the formula and a worked example built in.
