What is the foot (US survey) unit used for?

It is used mainly in U.S. land surveying, defining property boundaries, and in legacy geodetic datasets such as the State Plane Coordinate System.

What does femtometer measure?

A femtometer measures extremely small lengths typically at the nuclear or subnuclear scale in nuclear and particle physics.

Is this conversion practical for everyday measurements?

No, due to the large scale difference, the conversion is mostly intended for theoretical or computational uses.
