## Functions
U_CAPI int32_t | icu::umeas_getPrefixBase (UMeasurePrefix unitPrefix)
| Returns the base of the factor associated with the given unit prefix: the base is 10 for SI prefixes (kilo, micro) and 1024 for binary prefixes (kibi, mebi). More...
U_CAPI int32_t | icu::umeas_getPrefixPower (UMeasurePrefix unitPrefix)
| Returns the exponent of the factor associated with the given unit prefix, for example 3 for kilo, -6 for micro, 1 for kibi, 2 for mebi, 3 for gibi. More...
