"The numerical value always precedes the unit, and a space is always
used to separate the unit from the number. Thus the value of the
quantity is the product of the number and the unit, the space being
regarded as a multiplication sign (just as a space between units implies
multiplication). The only exceptions to this rule are for the unit
symbols for degree, minute, and second for plane angle, ?, , and ,
respectively, for which no space is left between the numerical value and
the unit symbol. [...]" ("The International System of Units (SI)".
