Units, Conversions and Engineering Accuracy

The groundwork under every engineering calculation: the SI system, converting between the three systems that meet on any project, and the difference between mass and force, gauge and absolute pressure, a temperature and a temperature difference. It adds dimensional analysis for checking any equation before you use it, significant figures and the safe direction to round, the units of all six disciplines, and the twelve most common unit errors with the way to catch each one. Ten worked examples, a quick conversion card, and a check list to print before issuing a calculation.
