Those fawking things should have huge warning labels on them. You know you could just go ahead and use the metric system for it's benefits instead of trying to make imperial untis perform like metric....
I needed to order some spare trailer axles, so I grabbed a tape and crawled under my trailer. I knew the spring perch distance I thought I needed. Used the tape and came up with a number that didn't make sense. Remeasured, still didn't make sense. I went and got another tape to compare thinking the first one might have stretched or been damaged. All the foot marks lined up, but the "inches" didn't.
I seriously considered tossing that tape into my contractor buddies truck for the ensuing funny, but decided against it.
Edit: Mine only had the tenths on it, not a combo tape like you're shown.
