Distance

Selection prerequisites: Two points, or one point and one straight object.

Measures the distance between two points, or the distance from a point to a straight object, using the distance units chosen on the Units panel of the Preferences dialog box.

To measure the distance between two points on a coordinate system in grid units, use the Coordinate Distance measurement instead.

The distance from a point to a line is the shortest distance from the point to the line and is measured along the perpendicular. The distance from a point to a ray or segment is defined to be the same as the distance from the point to the straight line that contains the ray or segment.
