This little book is super handy for anyone who makes stuff (or needs to look up things for the making of things) it’s filled with hundreds of tables, maps, formulas, constants & conversions. It’s tiny and I don’t ever leave home without it – Link & detailed contents – Link.

    This is a great reference book! I use it constantly. It is also part of a series, I know I have seen Pocket PC Ref which is a computer user/programmer version of the same design.
