For some reason I can't seem to be able to convert units without getting all mixed up. I can convert feet to inches to cm fine, but I can't convert units in a more complicated problem; for example, converting ft/sec to km/hour. I just get really mixed up and lose track of the numbers. ] I looked at multiple videos on youtube and I get it, but when I look at a problem its like gibberish to me. I know this is really easy math (I mean, I'm in calculus now so it shouldn't even be a problem, multiplying fractions) but I just can't do it. It's like I'm only dyslexic whenever I look at a unit converting problem...anyone have any advice for me?
