## Universal Constants and Unit Conversions

All the Universal constants or Physical/Chemical constants such as ‘Gravitational constant’, ‘Speed of light’, ‘Avogadro’s number’ etc are available in ZCubes in a way they can be used in functions. This video demonstrates how to use these constants in Z programming or spreadsheet computations using easy notations. ZCubes handles computations with ‘Units’ which is extremely useful in scientific computations.
