Also pulsars are highly regular astronomical clocks. Conversion of Units Estimates and Order-of-Magnitude Calculations Significant Figures Density varies with temperature and pressure. It would be necessary to measure both mass and volume very accurately in order to use the density of water as a standard. People have different size hands. Defining the unit precisely would be cumbersome. a millimeters b 50 microseconds c kilograms b and d . You cannot add or subtract quantities of different dimension. A dimensionally correct equation need not be true. Example 1 chimpanzee 2 chimpanzee is dimensionally correct. If an equation is not dimensionally correct it cannot be correct. If I were a runner I might walk or run 101 miles per day. Since I am a college professor I walk about 100 miles per day. I drive about 40 miles per day on workdays and up to 200 miles per day on vacation. On February 7 2001 I am 55 years and 39 days old. 55 yrf d J 39 d 20128 df 86 400 s J X 109 s 109 s.
