What Is This Tool?
This tool converts angular velocity measurements from degree per minute (°/min), a unit for relatively slow rotations per minute, into radian per day (rad/d), useful for describing slow rotational rates or orientation changes over a full day.
How to Use This Tool?
-
Enter the angular velocity value in degree per minute (°/min) into the input field.
-
Select degree per minute as the input unit and radian per day as the output unit.
-
Click the convert button to obtain the equivalent angular velocity in radian per day.
-
Review the result for use in long-duration rotational or precessional motion analysis.
Key Features
-
Converts degree/minute (°/min) to radian/day (rad/d) units accurately using a fixed conversion factor.
-
Supports applications in astronomy, spacecraft attitude control, geodesy, and slow instrumentation rotations.
-
Easy to use interface suitable for translating short time scale angular velocities into longer term equivalents.
Examples
-
Convert 2 °/min: 2 × 25.1327412287 = 50.2654824574 rad/d
-
Convert 0.5 °/min: 0.5 × 25.1327412287 = 12.56637061435 rad/d
Common Use Cases
-
Astronomical telescope tracking and slew rates involving slow angular displacement.
-
Describing rotation rates of planets, moons, or asteroids over long periods.
-
Specifying spacecraft attitude drift or spin rates for mission planning.
-
Mechanical rotation rates of radar or antenna assemblies requiring slow, precise motion control.
Tips & Best Practices
-
Confirm the angular velocity is relatively constant over the measurement period before conversion.
-
Use this conversion for applications where time scales span from minutes (input) to days (output).
-
Carefully verify unit selection to avoid mixing other angular velocity units.
-
Apply the tool for slow rotational motions where long-term angular displacement is relevant.
Limitations
-
Assumes angular velocity remains constant and linear scaling of time periods.
-
May not accurately capture irregular or highly variable rotational speeds.
-
Requires attention to precise time intervals because of the use of days in measurement.
Frequently Asked Questions
-
What does degree per minute represent?
-
Degree per minute (°/min) is an angular velocity unit indicating one degree of rotation every minute, used for relatively slow rotations.
-
Why convert degree/minute to radian/day?
-
Converting to radian per day is helpful to express slow rotational or orientation changes over 24 hours, important in astronomy and spacecraft monitoring.
-
Can this conversion be used for fast rotational speeds?
-
This conversion is intended for relatively slow angular velocities and may not be suitable for highly variable or rapid rotations.
Key Terminology
-
Degree per minute (°/min)
-
A unit of angular velocity indicating the angle in degrees that an object rotates through each minute.
-
Radian per day (rad/d)
-
A unit measuring angular velocity as radians rotated over a 24-hour period, used for slow, long-term angular changes.
