MICROMETER

A CARPENTER who only knew feet & inches WAS ASKED TO GET 10 - 2.45M BOARDS.

Q.   How many feet are in a 2.45m (meter) board?

A.   Accurately: We multiply (2.45 X 39.37 = 96.4565) inches rounded to 96 inches or 8 feet.

Metric & Imperial (a.k.a. feet & inches) measurements are often rounded to an "about" number.
