Yeah. So if we want to go between pounds and kilograms, what we can find is that one kg Is the same as two, So we can use this conversion to go between kg and pounds and so, uh if we have 192 kg what we're gonna want to do is use dimensional analysis to convert kilograms into pounds, dimensional analysis requires you to decide which units go on the top and the bottom of a fraction. We want our answer in pounds. So we're gonna want pounds on the top. We don't want our answer in kilograms. So kilograms is going to have to cancel out. Now once we have our units where we need them, we put our numbers next to our units. So we got to £0.20 over one kg mhm kilograms divided by kilograms, cancel out. And now we just put it into our calculators and we wind up getting 23 significant figures £422.4 as our answer. So whenever you want to convert from one unit to another, find the conversion factor and then set up your units. So the ones you don't want anymore cancel out. And the one that you do want is in the numerator
