They are also commonly used in medical practice. E.g. to work out
what's called the body mass index from a person's height and weight
in drug dose calculations.

The reason for their use seems to be twofold - 1, the people who
use them do not know very much mathematics (at least of the school
arithmetic kind); but 2, you can calculate with them whilst having both
hands
full!

An ancient book, "The Nomogram", Allcock & Jones, (Pitman, London, 1922)
discusses the maths behind their construction. V interesting, and
should be implementable in any software.
