UMEASURE_UNIT_SINGLE

A single unit, like kilojoule.

ICU 67

UMEASURE_UNIT_COMPOUND

A compound unit, like meter-per-second.

ICU 67

UMEASURE_UNIT_MIXED

A mixed unit, like hour+minute.

ICU 67

Enumeration for unit complexity. There are three levels:

- SINGLE: A single unit, optionally with a power and/or SI or binary prefix.

Examples: hectare, square-kilometer, kilojoule, per-second, mebibyte.

- COMPOUND: A unit composed of the product of multiple single units. Examples:

meter-per-second, kilowatt-hour, kilogram-meter-per-square-second.

- MIXED: A unit composed of the sum of multiple single units. Examples: foot+inch,

hour+minute+second, degree+arcminute+arcsecond.

The complexity determines which operations are available. For example, you cannot set the power

or prefix of a compound unit.

umeas_getPrefixBase() to find their corresponding values.
