Janka Hardness
The Janka scale is used to determine the 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.
