What are the units of measurement for tangential speed? For rotational speed?

Tangential speed: m/s, ft/s, cm/s, m/hr, km/hr, etc

Rotational speed: rev/min, rad/s, rad/min, rev/s, etc

Explanation:

The tangential speed is basically the linear speed with formula:

Tangential Speed = Linear distance / Time

Hence it has units of linear speed such as: m/s, ft/s, cm/s, m/hr, km/hr, etc

The rotational speed has the formula:

Rotational speed = angular displacement / time

Hence, it has units: rev/min, rad/s, rad/min, rev/s, etc
