Note that, just as for numbers, when a unit is divided by an identical unit (in this case, m/m), the result is 1or, as commonly phrased, the units cancel.. Direct link to Laura Sloma's post Why does this say d= rate, Posted 7 years ago. On the Fahrenheit scale, the freezing point of water is defined as 32 F and the boiling temperature as 212 F. Measurements are made using a variety of units. First, we need an equivalence. Here, the SI units are given along with their respective . have successfully converted the density of water from units of grams per milliliter to units of grams per liter. (When identical units divide to yield a factor of 1, they are said to cancel.) Using dimensional analysis, we can determine that a unit conversion factor has been set up correctly by checking to confirm that the original unit will cancel, and the result will contain the sought (converted) unit. dimensional analysis, so it's 5, so we have meters per second times hours, times hours, or you could say 5 meter hours per second. Now you're saying, "OK, The 5 times the 1, so we multiply the 5 times the 1, that's just going to give us 5. The trick is to remember to raise the QUANTITY and UNITS by the power. Note: We are ignoring a concept known as "significant figures" in this example. An abbreviated form of this equation that omits the measurement units is: \[\mathrm{\mathit{T}_{^\circ F}=\dfrac{9}{5}\times \mathit{T}_{^\circ C}+32} \nonumber \].
