The speed of a computer mouse. As everyone knows, Mickey was a cartoon mouse. But so is that device that is often used with a computer!
A “mickey” is the speed at which a computer mouse moves on a computer display and is used by computer scientists and programmers.
The speed is usually measured in mickeys-per-second. In case anyone is wondering, 1 mickey (the smallest measurable computer mouse’s movement) is equal to 1/200th of an inch (a little over 0.1 millimeter).
