What Is This Tool?

This converter changes angular velocity measurements from radians per second to revolutions per day. It helps translate fast rotational speeds used in engineering to slower rotations used in astronomy and geodesy.

How to Use This Tool?

  • Enter the value in radian per second (rad/s) you want to convert
  • Select 'radian/second [rad/s]' as the source unit
  • Choose 'revolution/day [r/d]' as the target unit
  • Click convert to see the result displayed in revolutions per day

Key Features

  • Converts radian/second (rad/s) to revolution/day (r/d) accurately based on defined rates
  • Provides unit definitions to support understanding of angular velocity
  • Suitable for use in engineering, astronomy, orbital mechanics, and geodesy
  • Browser-based and easy to use without the need for additional software

Examples

  • Convert 2 rad/s: 2 × 13750.98708314 = 27501.97416628 r/d
  • Convert 0.5 rad/s: 0.5 × 13750.98708314 = 6875.49354157 r/d

Common Use Cases

  • Specifying motor and shaft rotational speeds for mechanical and electrical engineering
  • Describing joint and angular rates in robotics and control systems
  • Expressing slow planetary or satellite spin rates in astronomy and space science
  • Reporting Earth rotation and long-term angular drift in geodesy and timekeeping

Tips & Best Practices

  • Use this conversion when needing to express fast angular velocities in slower time frames
  • Ensure input values are appropriate to avoid precision loss due to large numeric factors
  • Apply this unit when relating engineering rotational data to astronomical time scales

Limitations

  • Large numeric conversion factors can cause precision issues with extremely high or low angular velocities
  • Primarily intended for translating fast rotations to slow rotation rates measured over a day
  • Not ideal for applications requiring instantaneous angular velocity measurements

Frequently Asked Questions

What is a radian per second?
A radian per second (rad/s) is the SI unit of angular velocity, representing the angle in radians swept per second.

When should I convert rad/s to revolution/day?
Convert rad/s to r/d when you need to express angular velocity as slow rotations occurring over a day, commonly in astronomy and geodesy.

Can this converter be used for all angular velocity values?
While it works for many values, very large or very small angular velocities may experience precision loss due to large conversion factors.

Key Terminology

Radian/second (rad/s)
SI derived unit of angular velocity measuring the angle in radians swept per second.
Revolution/day (r/d)
Unit of angular velocity representing one complete rotation in one day.
Angular velocity
The rate of change of angular displacement over time.
