Wolfram Language (aka Mathematica) is the best for doing scientific computing with physical unit dimensions.

See: https://reference.wolfram.com/language/guide/Units.html

> The units framework [of Wolfram Language] integrates seamlessly with visualization, numeric and algebraic computation functions. It also supports dimensional analysis, as well as purely symbolic operations on quantities.

Note that Mathematica units impose a very large runtime penalty, making them unsuitable for a lot of applications
