Frequently Asked Questions
-
What does degree per day [°/d] measure?
-
Degree per day measures angular velocity as degrees rotated over a 24-hour period, often used for celestial body motions and slow rotations.
-
Why convert from degree/day to revolution/second?
-
Converting to revolution/second translates slow angular motions into standard rotational frequencies, useful in engineering and scientific contexts.
-
Can this conversion handle non-uniform rotations?
-
No, the conversion assumes uniform rotation; irregular motions require other analysis techniques.
Key Terminology
-
Degree/day [°/d]
-
An angular velocity unit expressing degrees rotated over one day, often utilized in astronomy for slow rotational rates.
-
Revolution/second [r/s]
-
A measure of angular speed counting full rotations completed each second, equivalent to rotational frequency in hertz.
