Function getUomKind

getUomKind(uom: string): undefined | UomKind

Classifies a unit of measure as mass, volume, or countable. Standardizes the input first (via standardizeUom), so aliases like "grams" or "lbs" are accepted. Returns undefined for unrecognized units.

Parameters

uom: string
The unit of measure to classify (canonical or alias form).

Returns undefined | UomKind

The unit's kind, or undefined if the unit isn't recognized.

Example

getUomKind("kg")   // Returns "mass"
getUomKind("floz") // Returns "volume"
getUomKind("pcs")  // Returns "count"
getUomKind("xyz")  // Returns undefined
