Agreed...I know a lot of people measure rollout in metric but for some reason people around here always use imperial units. I've just changed over my rollout sheet to be metric. Will probably take some getting used to but it's a start.
I remember in my engineering classes I always HATED doing things in imperial units. Metric was always so much easier to work with. The most annoying thing was getting to an exam and having the EXACT same problem we've done before but having it changed from metric to imperial units. ICK!
