Overview ¶
Package ucum provides UCUM (Unified Code for Units of Measure) normalization for FHIR quantity search parameters.
UCUM is the standard unit system used in FHIR for quantities. This package normalizes units to canonical base units to enable cross-unit search (e.g., 10mg = 0.01g).

Functions ¶
func GetCanonicalUnit ¶
GetCanonicalUnit returns the canonical unit for a given code. Returns the original code if not found.
func IsKnownUnit ¶
IsKnownUnit returns true if the unit code is recognized for normalization.
Types ¶
type NormalizedQuantity ¶
type NormalizedQuantity struct {
Value float64 // Normalized value in canonical units
Code string // Canonical unit code
}
NormalizedQuantity represents a quantity normalized to canonical UCUM units.
func Normalize ¶
func Normalize(value float64, code string) NormalizedQuantity
Normalize converts a quantity to its canonical UCUM form. Returns the original values if the unit is not recognized.
func NormalizeWithSystem ¶
func NormalizeWithSystem(value float64, system, code string) NormalizedQuantity
NormalizeWithSystem converts a quantity considering both system and code. For UCUM system (http://unitsofmeasure.org), it applies normalization. For other systems, it returns values unchanged.
type UnitConversion ¶
type UnitConversion struct {
CanonicalCode string // The canonical unit code (e.g., "g" for mass)
Factor float64 // Multiply original value by this to get canonical
}
UnitConversion defines a conversion from a unit to its canonical form.
