Using Structural Error for Mesh Quality Assessment (averaged vs unaveraged results)

Determining whether mesh is fine enough using the stress Structural Erro which is the difference between averaged vs unaveraged stress values is explained in this video.

Could you kindly explain how ansys works out 530 mJ of structural error based on a difference of 44 MPa between averaged and unaveraged in your example?

The unit of structural error is Joule, why not Pascal? How is structural error defined?
