JANKA -WOOD HARDNESS- SCALE

The Janka scale is used to determine the 'approximate' relative hardness of particular domestic or exotic wood species. The Janka test measures the amount of force required to embed a 0.444" steel ball into the wood to half of its diameter. Woods with a higher rating are harder than woods with a lower rating. The scale used in the table is pounds-force.
