Degree per Hour (°/h)
Definition: The slowest common degree-based angular velocity unit, measuring degrees of rotation completed per hour.
History: Derived the same way as degree per minute, extended to the hour timescale for describing very gradual angular changes.
Current use: Used to describe extremely slow processes like the apparent rotation of the sky as seen from Earth, clock hour-hand motion, or slow-drift calibration testing of gyroscopes.
Radian per Minute (rad/min)
Definition: A scaled-down version of the radian per second, expressing how many radians an object rotates through in one minute rather than one second.
History: Formed the same way as any SI unit divided by a non-SI time unit, used whenever a rotation is slow enough that per-second figures would be inconveniently small.
Current use: Occasionally used in slow-rotation contexts such as antenna positioning, industrial mixers, or clock mechanisms where per-second radian values would read as tiny decimals.

How Angular Velocity Conversion Works
The Formula
Every unit here is defined by a fixed multiplier relative to the radian per second. To convert a value from one unit to another:
result = value × (factor of "From" unit ÷ factor of "To" unit)
For Degree per Hour → Radian per Minute: multiply by 0.000290886. For example, 1 °/h × 0.000290886 = 0.000290886 rad/min.
Radians, Degrees, and Revolutions
Angular velocity can be measured in three fundamentally different angle units. The radian is the mathematically natural unit — one full turn equals 2π radians — and is what appears directly in physics formulas like v = ωr, linking angular speed to linear speed through a radius. The degree divides a full turn into 360 familiar parts and is more intuitive for humans, which is why robotics and sensor datasheets favor it. The revolution simply counts whole turns, making it the natural choice for anything with a spinning shaft — engines, motors, hard drives, turbines — since RPM (revolutions per minute) is the number a tachometer actually displays.
From Angular Velocity to Linear Speed
Angular velocity and linear speed are related through the radius of rotation by v = ωr, where ω is angular velocity in radians per second and r is the distance from the rotation axis. This is why a point near the center of a spinning wheel moves much slower than a point on its rim, even though both share the same angular velocity — the outer point simply has a larger radius to sweep through. This relationship is fundamental in mechanical engineering for converting a motor's rotational speed into the linear speed of whatever it drives, such as a conveyor belt or vehicle wheel.
Example
1 °/h equals 0.000290886 rad/min. For scale, a typical car engine idling at around 800 RPM is spinning at roughly 17280131 °/h, while a washing machine's spin cycle at around 1,200 RPM works out to about 25920197 °/h.
Frequently Asked Questions
How many Radians per Minute are in 1 Degree per Hour?
1 Degree per Hour (°/h) equals exactly 0.000290886 Radians per Minute (rad/min).
Why does physics use radians per second instead of RPM?
Radians are the angle unit that makes calculus-based physics formulas work cleanly — derivatives and integrals of trigonometric functions only simplify nicely when angles are in radians. RPM is easier for humans to picture (whole turns per minute), so engineering datasheets and tachometers use it, but the underlying physics equations almost always convert back to radians per second first.
How do I convert RPM to radians per second?
Multiply the RPM value by 2π and divide by 60, since each revolution is 2π radians and there are 60 seconds in a minute. This converter applies that exact factor (0.1047197551) automatically, so entering a value in revolutions per minute and selecting radians per second as the target gives the precise result instantly.
How accurate are these conversions?
Every conversion factor used here is derived from the exact mathematical relationships between radians, degrees, and revolutions (e.g. 1 revolution = 2π radians = 360 degrees exactly) — results are limited only by floating-point display precision, not by rounded conversion constants.
