Units; Calculators (17.2) Fundamental Quantities. Search. one of the three states of matter. In dimensional analysis, a ratio which converts one unit of measure into another without changing the quantity is called a conversion factor.For example, kPa and bar are both units of pressure, and 100 kPa = 1 bar.The rules of algebra allow both sides of an equation to be divided by the same expression, so this is equivalent to 100 kPa / 1 bar = 1. For example, if we observe experimentally that an object’s potential energy is related to its mass, its height from the ground, and to a gravitational force, then when multiplied, the units of mass, height, and the force of gravity must give us units corresponding to those of energy.
