    you are looking for a length measurement based off of a weight measurement?

    There is no correlation between a weight (1.5 lbs, or w.e the number was) and a length. There either needs to be more information, or you arent looking for millimeters

    that is definitely better. hahaha well in 1 pound there are 453.59 grams. so you will have to set up some conversion tables. \[1.5lb * \frac{ 453.59 g }{ 1 lb }\] the pounds will then cancel, and then you are left multiplying the 1.5 by 453.59, and the units will come out to be grams because that is the only thing left. you will simply have to do the same thing for the other lung.

    they are two separate problems because you are only trying to convert them both to grams, or am i mistaken?

    nope, first what you are going to want to do is convert both lbs to grams because you are looking for the difference between the two in grams. which means you are subtracting the smaller one from the larger one. so bascially the 1.5 and 1.25 dont interact until after they are converted.

    well that is another way to approach the problem to get the same answer, and you will only have to convert to grams once, so sure lets go about it that way. so you will subtract 1.25 from 1.5: 1.5-1.25 = .25lbs

    nope, other way around haha, if you look up a few posts, there are 453.59g in 1 lb. so you are going to set up the conversion table of: .\[.25lbs*\frac{ 453.59g }{ 1 lb }\] the lbs will cancel and you will only be left with g, so alll you do is multiply .25 by 453.59 g
