*To calculate tip speed from RPM, use the formula: Tip Speed (ft/min) = 2π × Radius (ft) × RPM. Simply multiply the radius of the rotating object (in feet) by the RPM (revolutions per minute) and then multiply by 2π. This formula provides the tip speed in feet per minute.*

## RPM to Tip Speed Calculator

**Tip Speed:** — ft/s

Certainly, here’s a table showing RPM values and their corresponding tip speeds in feet per minute (ft/min), assuming a constant radius of 1 foot:

RPM | Tip Speed (ft/min) |
---|---|

100 | 628.32 |

500 | 3,141.59 |

1,000 | 6,283.18 |

2,000 | 12,566.37 |

5,000 | 31,415.93 |

10,000 | 62,831.85 |

20,000 | 125,663.71 |

You can calculate tip speeds for other radii by multiplying the radius (in feet) by the RPM and then by 2π.
