Charpy impact test results are measured in joules, the SI unit for energy. This is simply the amount of work performed by a 1-newton force pushing a sample by 1 m in the direction of the force. This value can be used to calculate the impact energy in J/m2 by dividing the joule value by the sample's cross-sectional area at the sample notch.
