And thanks for the heads up about 2.54cm/inch. I've been using some sewing books which make recommendations of rounding to the 10th rather than 100th perhaps because they were using pencil& paper, and it worked well enough for them personally. This is ultimately garbage advice, so thanks for pointing that out.
It's not that the advise is complete garbage, it depends on what you want. It's just that you had 1 in = 72.72 pts, which is 4 significant digits and 1 in = 2.5 cm, which has only two. It's best to have the same number of significant digits for all your conversions. :)
