Are there any languages that allow units?

Julia's Unitful package is one of my favorites. https://github.com/PainterQubits/Unitful.jl

Tangentially related, LaTeX's siunitx package makes typesetting units a joy. Is there similar functionality available in HTML/Markdown ecosystems? https://ctan.org/pkg/siunitx
