Degree per Hour Squared (°/h²)

Definition: An extremely fine-grained angular acceleration unit describing changes in degrees-per-hour rotational speed over an hour.

History: The hour-scaled extension of the same degree-based convention, reserved for extraordinarily gradual angular speed changes.

Current use: Rarely used outside highly specialized scientific instrumentation tracking near-imperceptible rotational drift over long periods.

Degree per Second Squared (°/s²)

Definition: An angular acceleration unit expressed in degrees, describing how many degrees per second of rotational speed an object gains each second.

History: A natural degree-based counterpart to the radian per second squared, favored wherever degrees are already the working angle unit for describing rotation.

Current use: Common in robotics, motor control systems, and gyroscope/IMU datasheets, since degree-based figures are more intuitive to engineers than radian-based ones.

How Angular Acceleration Conversion Works

The Formula

Every unit here is defined by a fixed multiplier relative to the radian per second squared. To convert a value from one unit to another:

result = value × (factor of "From" unit ÷ factor of "To" unit)

For Degree per Hour Squared → Degree per Second Squared: multiply by 7.71602E-08. For example, 1 °/h² × 7.71602E-08 = 7.71602E-08 °/s².

Angular Acceleration and Torque

Angular acceleration is the rotational counterpart of linear acceleration, and it plays the same role in rotational dynamics that ordinary acceleration plays in Newton's second law. Just as force equals mass times acceleration (F = ma), torque equals moment of inertia times angular acceleration (τ = Iα) — a heavier flywheel (larger moment of inertia) needs more torque to reach the same spin-up rate as a lighter one. This relationship is central to motor sizing, drivetrain design, and any engineering problem involving how quickly a rotating system can speed up or slow down.

Spin-Up and Spin-Down Rates in Practice

Angular acceleration shows up whenever a rotating system's speed is changing rather than holding steady — an electric motor ramping up from a standstill to its rated RPM, a turbine slowing down after a shutdown, or a centrifuge accelerating a sample to operating speed. Engineers use this unit to specify how quickly a system reaches its target rotational speed, which affects everything from motor controller design to how much mechanical stress a fast spin-up puts on a shaft or bearing.

Example

1 °/h² equals 7.71602E-08 °/s². For scale, a washing machine motor accelerating from a standstill to a 1,200 RPM spin cycle in about 10 seconds is averaging roughly 120 RPM per second of angular acceleration — equivalent to about 9.33123E+09 °/h² on this scale (120 RPM/s converted to RPM per minute squared).

Frequently Asked Questions

How many Degrees per Second Squared are in 1 Degree per Hour Squared?

1 Degree per Hour Squared (°/h²) equals exactly 7.71602E-08 Degrees per Second Squared (°/s²).

What's the difference between angular velocity and angular acceleration?

Angular velocity describes how fast something is currently spinning (e.g. RPM or radians per second); angular acceleration describes how quickly that spin rate is changing. A motor holding a constant 3,000 RPM has angular velocity but zero angular acceleration; the same motor ramping up from 0 to 3,000 RPM has significant angular acceleration during the ramp-up period.

How does angular acceleration relate to torque?

Torque equals moment of inertia times angular acceleration (τ = Iα), the direct rotational analog of Newton's second law (F = ma). A motor with more available torque, or a load with less rotational inertia, can achieve a higher angular acceleration — this is exactly why lighter flywheels spin up faster than heavier ones given the same motor.

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), squared for the time component — results are limited only by floating-point display precision, not by rounded conversion constants.
