Unit Expression Syntax Rules
See the
UCUM Specification for full descriptions of grammar and syntax rules.
 A UCUM
defined prefix can be applied to metric units, e.g. kg for
kilogram (where k is the prefix kilo and g is the base unit gram).
 Simple units may be
raised to a power by appending an integer number to the end of the
unit term, e.g., m2 for a square meter. Negative exponents must be
preceded by a minus sign (''). Positive exponents may be preceded by
a plus sign ('+') although the sign may be omitted.
 All units can be combined in an
algebraic term using the operators for multiplication (period '.')
and division (solidus '/'), e.g., 2.m.
 No blanks are allowed within the unit expression.
 Multiple terms in an expression must be separated by an arithmetic
operator  either the multiplication operator (.) or the division
operator (/), e.g., 2.m, not 2m.
 The multiplication operator (.) must be explicity specified; it is never
assumed.
 While the multiplication operator (.) must appear between two unit terms,
the division operator (/) may appear at the beginning of the expression,
indicating inversion of the following term. So /dL is a valid unit
indicating "per deciliter". However, the division
operator normally appears between two terms.
 Terms are evaluated from left to right, with multiplication and
division having the same precedence.
 Parentheses
may be used to override normal lefttoright evaluation
of an expreession. For example kg/m.s2 divides kg by m and multiplies
the result by s2. kg/(m.s2) divides kg by the result of multiplying
m by s2.

demonstration purposes only. Before relying on the unit conversions
produced by this tool it is your obligation to perform your own tests
to verify that the results are sufficiently accurate for your purposes.
