Dimensional Analysis - Kentchemistry.com If you want to check whether a given equation is correct or not, you can compute the dimensions on both sides (LHS and RHS), if both dimensions are equal, then the equation is correct, otherwise, it's wrong. Questions include m/s to mph, liters to cups, and pounds to kilograms. It might jump out of you, well, if we can get rid of this hours, if we can express it in terms of seconds, then that would cancel here, and we'd be left with just the meters, which is a unit of distance Your dashboard will track each student's mastery of each skill. To mark a scale on a thermometer, we need a set of reference values: Two of the most commonly used are the freezing and boiling temperatures of water at a specified atmospheric pressure. \hline \text { Mar. seconds, they give it in hours, so they say the time is equal to 1 hour.
