Final velocity is measured in units of distance per unit time. The most common units are:

* Meters per second (m/s): This is the standard unit in the metric system.

* Kilometers per hour (km/h): This is often used for road speeds.

* Miles per hour (mph): This is the standard unit in the US and some other countries.

* Feet per second (ft/s): This is sometimes used in engineering applications.

The specific unit used will depend on the context of the problem.
