I admit to all the FACS teachers out there - when I had a student who could not work fractions and you gave him or her a worksheet to do that involved converting measurements (how many Tbsp in a cup sort of thing) I just pulled up this site and let them do it this way. I wasn't going to be able to teach several years of math just to cover one assignment. And frankly if I needed to do this in my own this is exactly how I'd do it.
