This invaluable reference manual provides well-organized tables of over 2100 conversion factors for measures ranging from time and length to metabolic rate and viscosity. An index defines each term: acres, dynes, joules, liters, knots, and so on. Also included are guides to abbreviations, to physical and technical dimensions, and to the système internationale (SI). This slim but invaluable reference manual provides scientists, engineers, and students with well-organized tables of conversion factors for the varied systems humans have devised to measure physical quantities.
