Here are some other units you might encounter:

* Knots (kt): Used primarily for nautical speeds. One knot is equal to one nautical mile per hour.

* Feet per minute (ft/min): Used in some specific applications where a slower speed is relevant.

It's important to note that velocity is a vector quantity, meaning it has both magnitude (speed) and direction. So, you might also need to specify the direction of the velocity, for example, "10 feet per second north."
