Janka Hardness Scale
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.
