UnitConversion

An exact conversion between two units of the same kind.

Applied as to = from * numerator / denominator + offsetNumerator / offsetDenominator. Every field is an integer, and that is deliberate: these are definitions rather than measurements, and a definition stored as a rounded decimal is an approximation wearing a definition's provenance.

basis names the definition each factor comes from. A conversion with no basis does not belong in this system: opsinjs does not own a clinical number, and the ones it does carry are the ones that are true by definition rather than by measurement.
