Dimenso is a library for performing dimension-aware calculations in C# and Java. It offers numeric types that have dimensions, expressed in terms of base dimensions M (mass), L (length), T (time), and Q (electric charge). Playing to the strengths of each language, C# types have operator overloads to allow them to be used as numbers, while Java types mimic the BigDecimal with respect to arithmetic methods.
