What Is This Tool?
This unit converter allows you to transform values expressed in revolution per day (r/d), a measure of very slow angular velocity, into revolution per minute (r/min), which is a more common unit for quicker rotational speeds. It is helpful in contexts ranging from astronomy to mechanical engineering.

-
10 revolution/day = 10 × 0.0006944444 = 0.006944444 revolution/minute
Common Use Cases
-
Describing slow rotation rates of celestial bodies like planets and moons in astronomy.
-
Analyzing spin rates of spacecraft or spin-stabilized satellites over long periods.
-
Monitoring engine and drivetrain speeds in automotive diagnostics.
-
Controlling rotational speeds of electric motors, fans, and pumps in industrial settings.
-
Managing speeds of laboratory centrifuges and machining spindles.
Tips & Best Practices
-
Use this converter for clarity when moving between very slow and faster rotational speed units.
-
Double-check the context to ensure appropriate units are being compared.
-
Be aware that converting very slow rates may produce very small decimal values.
-
Always consider the limitations when measuring extremely low velocities.
Limitations
-
Conversion from revolution/day to revolution/minute results in very small fractional values which can be less intuitive.
-
Measurement precision and rounding can impact accuracy with very low velocity values.
-
Not suitable for contexts requiring extremely high precision or rapid rotational speeds.
Frequently Asked Questions
-
What does revolution/day measure?
-
Revolution/day measures angular velocity as one complete rotation occurring over a full day, useful for describing very slow rotation rates such as those in astronomy.
-
Why convert revolution/day to revolution/minute?
-
Converting to revolution/minute allows translating slow rotational speeds into faster, practical units commonly used in mechanical and industrial applications.
-
Can I use this conversion for high-speed rotations?
-
This conversion is focused on slow rotations and converting very slow speeds to revolution per minute will result in small decimal values; it may not be ideal for high-speed scenarios.
Key Terminology
-
Revolution/day [r/d]
-
A unit measuring angular velocity as one complete rotation per day, used mainly for very slow rotations in astronomy and geodesy.
-
Revolution/minute [r/min]
-
A unit representing the number of complete turns around an axis occurring in one minute, commonly used in mechanical and industrial contexts.
-
Angular velocity
-
A measure of how fast an object rotates or revolves relative to another point, expressed in radians per second or revolutions per time unit.
