Number parameters represent dialog number fields of the corresponding
menu command. They specify integer or decimal numbers. Simply type a
number after the equal sign. If parameters require physical units, plain
numbers are interpreted as being specified in SI base units (m, s, g).
You may append derived units to trigger conversion of the value to SI
base units. Allowed derived units are: um, mm, cm, km, in, ug, mg, cg,
kg.
Examples:
Fixc=0
Wdt=2 is the same as Wdt=2m
Hgt=12.675cm is the same as Hgt=0.12675m
Hgt=5.5in is the same as Hgt=0.1397m
