    It seems to me that Haskell would be a great language for such a thing, ensuring correctness at compile time through the type system, e.g. using the units package https://hackage.haskell.org/package/units https://github.com/goldfirere/units/tree/master/units

    It even has nice features like: "The laws of nature have dimensions, and they hold true regardless of the units used. For example, the gravitational force between two bodies is (gravitational constant) * (mass 1) * (mass 2) / (distance between body 1 and 2)^2, regardless of whether the distance is given in meters or feet or centimeters. In other words, every law of nature is unit-polymorphic."

    "The units package supports unit-polymorphic programs ..."

hgeometry - HGeometry is a library for computing with geometric objects in Haskell. It defines basic geometric types and primitives, and it implements some geometric data structures and algorithms. The main two focusses are: (1) Strong type safety, and (2) implementations of geometric algorithms and data structures that have good asymptotic running time guarantees.
