Sure, if you consider 3,200 feet as "measured in feet" [1]. Anything can technically be measured in feet. When you said that I assumed you meant they were like 20-30 feet thick, not over half a mile.
From a NASA website[0]: Saturn’s rings are incredibly thin. The main rings are generally only about 30 feet (10 meters) thick, though parts of the main and other rings can be more than a mile, or several kilometers, thick.
