text: Dimensional correctness as part of type checking has been studied since 1977.
  Implementations for Ada and C++ were described in 1985 and 1988.
  Kennedy's 1996 thesis describes an implementation in Standard ML, and later in F#. There are implementations for Haskell, OCaml, and Rust, Python, and a code checker for Fortran.<br />
  Griffioens 2019 thesis extended Kennedys Hindley–Milner type system to support Hart's matrices.
  McBride and Nordvall-Forsberg show how to use dependent types to extend type systems for units of measure.
  Mathematica 13.2 has a function for transformations with quantities named NondimensionalizationTransform that applies a nondimensionalization transform to an equation. Mathematica also has a function to find the dimensions of a unit such as 1 J named UnitDimensions. Mathematica also has a function that will find dimensionally equivalent combinations of a subset of physical quantities named DimensionalCombations. Mathematica can also factor out certain dimension with UnitDimensions by specifying an argument to the function UnityDimensions. For example, you can use UnityDimensions to factor out angles. In addition to UnitDimensions, Mathematica can find the dimensions of a QuantityVariable with the function QuantityVariableDimensions.
