The Janka test measures the force
required to embed a 11.28 millimeter (0.444 inch) steel ball into wood to
half its diameter. This method was chosen so that the result would leave an
indention 100 square millimeters in size. It is one of the best measures of
the ability of a wood species to withstand denting and wear. It is also a
good indicator of how hard a species is to saw or nail.
