What Is This Tool?
This tool converts angular velocity measurements from degree per hour (°/h), a unit often used to express slow rotation rates, into revolution per minute (r/min), a common unit for rotational speed in mechanical systems.
How to Use This Tool?
-
Enter the angular velocity value in degree/hour (°/h).
-
Select the 'degree/hour' as the input unit.
-
Choose 'revolution/minute' as the output unit.
-
Click the convert button to obtain the result in r/min.
Key Features
-
Converts angular velocity from degree/hour to revolution/minute accurately.
-
Browser-based and user-friendly interface for quick conversions.
-
Provides example conversions for easy reference.
-
Supports applications in astronomy, aerospace, and mechanical diagnostics.
Examples
-
Convert 10 °/h to revolution/minute: 10 °/h equals 0.000462963 r/min.
-
Convert 100 °/h to revolution/minute: 100 °/h equals 0.00462963 r/min.
Common Use Cases
-
Describing Earth's rotation speed and other slow planetary rotations in degrees per hour.
-
Measuring errors and drift rates in telescope and antenna tracking systems.
-
Quantifying low-rate attitude changes in spacecraft and inertial navigation.
-
Translating slow angular velocity values into standard mechanical speed units for machinery and motor diagnostics.
Tips & Best Practices
-
Ensure input values represent slow angular rates typical for degree/hour measurements.
-
Cross-check conversions when dealing with very low speeds due to possible rounding.
-
Use the converter for fields like astronomy, aerospace, and engineering to ensure unit consistency.
Limitations
-
Degree/hour measures very slow angular velocities while revolution/minute is suited for faster rotations.
-
Converted values are often very small decimals, which might lead to precision loss.
-
Rounding errors can occur when converting for extremely low-speed measurements.
Frequently Asked Questions
-
What does degree per hour measure?
-
Degree per hour (°/h) denotes angular velocity representing how many degrees an object rotates in one hour, often used to describe slow rotations like Earth's movement.
-
When should I use revolution per minute?
-
Revolution per minute (r/min) is ideal for specifying rotational speed of engines, motors, and machinery where speeds are expressed in full turns per minute.
-
Why are conversions from degree/hour to revolution/minute resulting in very small numbers?
-
Because degree/hour measures much slower rotations compared to revolution/minute, converted values tend to be very small decimals reflecting the slower angular velocity.
Key Terminology
-
Degree/hour [°/h]
-
A unit of angular velocity indicating the angle in degrees that changes per hour, often used for slow rotation rates such as planetary or spacecraft attitude drift.
-
Revolution/minute [r/min]
-
A unit measuring how many full turns an object completes around an axis each minute, widely used in mechanical and electrical engineering.
-
Angular velocity
-
The rate of change of angular position of a rotating object, typically measured in units like degrees per hour or revolutions per minute.
