Unit Specification
Unit specification allows you to specify the unit of a given value, which may or may not be a canonical unit.
Usage
Generally, unit specifications are used in expressions when defining a certain quantity. This allows you specify any applicable unit to a value while the underlying calculations remain the same. That is, unit specification cannot be used to convert a value from one unit to another.
A unit specification consists of a unit name enclosed in curly braces. This can be done for numerical values (integer and real) and the result is always a real type value.
10{cm} 100.0 millimeter is canonical unit for distance(3+4){m} 7000.0 units can be applied to subexpressions15{in} + 45{mm} 426.0 mixing units in an expression is allowed30{centimetres} 300.0 you can use unit name in specification

Built-in Units
Both built-in and custom units can be used in unit specification. Some built-in units have suffixes, for example degree° and mircosecond µs, and alternative forms that can be used in expressions. Units marked "Canonical" are canonical units for quantities and used internally by Visual Components Premium 4.8 to store and calculate values.
Note: Internally, 1 unit of Time is 1 second, 1 unit of Distance (Length) is 1 millimeter, and 1 unit of Speed is 1 millimeter per second.
