What is Janka Hardness? The test measures the force required to push a steel ball with a diameter of 0.444 inches (slightly larger than 7/16") into the wood to a depth of half the ball's diameter. Red Oak: 1,260 lbs on the Janka scale. Maple, N. American: 1,450 lbs on the Janka scale What is Specific Gravity? The weight of a particular volume of wood compared to the weight of the same volume of water. i.e. Water's specific gravity is 1. Most wood has a specific gravity that is less than 1, this is why it floats. Lignum vitae has a specific gravity of 1.05 and will sink when put in water.
