Janka rating, also known as Janka hardness test, is a measure of the hardness of wood. It is a standardized test that measures the amount of force required to embed a small steel ball into a piece of wood. The Janka rating is expressed in kN (kilonewton), and the higher the rating, the harder the wood.

The Janka rating is commonly used to determine the suitability of a particular wood species for use in flooring, furniture, and other applications where durability is important. Some woods with high Janka ratings include Brazilian Walnut, Hickory, and Brazilian Cherry, while woods with lower Janka ratings include Pine and Cedar.

It is important to note that while the Janka rating can provide a useful indication of a wood's hardness, it does not necessarily reflect other important characteristics of the wood, such as its resistance to decay, its stability, or its appearance.
