This work provides material that clearly defines and comments on SI quantities and units used to describe such properties as mass, force, weight, temperature, pressure, angle, moment of inertia and kinetic energy. It gives descriptions of the two classes of units, base and derived, that make up SI, providing clear guidance on writing SI symbols correctly. Also included are rules for conversion and rounding, and numerous easy-to-understand tables.
