What Is This Tool?
This tool converts angular velocity values from degree per day (°/d) to revolution per hour (r/h), helping users translate very slow rotations measured in degrees over a day into revolutions per hour which are more commonly used in machinery and scientific contexts.
How to Use This Tool?
- Enter the angular velocity value in degree per day (°/d)
- Select the target unit as revolution per hour (r/h)
- Apply the conversion using the provided factor
- Review the converted result expressed in revolutions per hour
Key Features
- Simple conversion between degree/day and revolution/hour angular velocity units
- Applicable for astronomy, aerospace, and industrial slow rotation measurements
- Includes conversion factor and practical examples
- Browser-based and easy to use without installation
Examples
- Convert 10 °/d to r/h: 10 × 0.0001157407 = 0.001157407 r/h
- Convert 100 °/d to r/h: 100 × 0.0001157407 = 0.01157407 r/h
Common Use Cases
- Reporting apparent motion of solar system bodies in astronomy
- Expressing slow rotation or precession rates of planets or spacecraft
- Setting telescope or instrument tracking rates for slow-moving celestial objects
- Specifying slow rotational speeds for large industrial equipment like rotary kilns
- Monitoring rotations for solar trackers and antenna mounts
Tips & Best Practices
- Use this conversion to integrate slow angular velocities expressed in degrees/day into faster unit contexts
- Ensure consistency by applying the exact conversion factor 0.0001157407
- Be mindful of the small numerical results and use appropriate precision
- Avoid using this conversion for fast rotations beyond slow angular velocity ranges
- Consider the assumption of constant angular velocity over the time period
Limitations
- Assumes angular velocity remains constant over the given time intervals
- May not be accurate for variable rotation rates or fast angular speeds
- Results may be very small and require careful numerical handling
- Degree/day is best suited for very slow motions, so conversion to faster scales has inherent constraints
Frequently Asked Questions
- What does degree per day (°/d) represent?
- Degree per day is an angular velocity unit expressing angular displacement in degrees over a 24-hour period, typically used to describe very slow rotational movements.
- Why convert degree/day to revolution/hour?
- Converting degree/day to revolution/hour helps compare slow angular velocities in contexts where revolutions per hour are standard, such as machinery or astronomical instrumentation.
- Can this conversion handle fast rotation speeds?
- No, degree/day is suited for slow angular velocities, and using this conversion for high-speed rotations is not recommended.
Key Terminology
- Degree/day [°/d]
- An angular velocity unit representing degrees rotated over one day, used for describing very slow rotation rates.
- Revolution/hour [r/h]
- An angular velocity unit measuring the number of full 360° rotations completed in one hour.
