What Is This Tool?
This tool converts angular velocity measurements from degree per hour, a unit representing slow angles changes over hours typically used in astronomy and aerospace, to revolution per second, a unit used for faster rotational speeds common in mechanical systems.
How to Use This Tool?
-
Enter the value in degree per hour (°/h) you want to convert.
-
Select 'degree/hour' as the input unit and 'revolution/second' as the output unit.
-
Click the convert button to get the equivalent value in revolution per second.
Key Features
-
Converts degree/hour (°/h) to revolution/second (r/s) accurately.
-
Supports angular velocity units relevant for astronomy and engineering.
-
Browser-based and user-friendly interface for quick conversions.
Examples
-
15 degree/hour equals 1.1574e-5 revolution/second.
-
360 degree/hour equals 0.0002777778 revolution/second.
Common Use Cases
-
Calculating Earth's rotation rate or other slow planetary rotations.
-
Determining telescope or antenna drift in astronomical pointing systems.
-
Measuring attitude drift rates in spacecraft or inertial navigation setups.
-
Specifying motor shaft speeds and rotational frequencies in engineering tests.
-
Reporting rotation rates of scientific instruments or devices like pulsars.
Tips & Best Practices
-
Use degree/hour for low angular velocities where precision over hours matters.
-
Switch to revolution/second for faster rotations or when frequency details per second are required.
-
Verify unit selection carefully to ensure accurate interpretation of results.
Limitations
-
Degree per hour is ideal for very slow angular changes but not suitable for high-speed rotations.
-
Revolution per second is best for rapid spins; converting very small degree/hour values may produce very tiny decimal outputs requiring precise instruments.
Frequently Asked Questions
-
What is degree per hour used for?
-
Degree per hour expresses slow angular velocity changes, often applied in describing Earth's rotation, telescope tracking errors, or spacecraft attitude drift.
-
How does revolution per second relate to frequency?
-
Revolution per second measures how many full rotations occur each second and corresponds directly to rotational frequency in hertz.
-
Can I use this converter for fast spinning motors?
-
Yes, converting angular velocity to revolution per second suits fast rotating machinery like motors, servos, or turbines.
Key Terminology
-
Degree/hour (°/h)
-
A unit of angular velocity expressing the rate of angle change in degrees per hour, used mainly for slow rotations.
-
Revolution/second (r/s)
-
A unit measuring the number of complete rotations an object makes each second, equating directly to rotational frequency.
