I work in the construction industry. There are a number of standard styles that everyone uses. I measure for window coverings with a tape that reads only in inches ( 12,13,14 ...) You always write down measurements width first. We had a printer do up a work order form for us and they inadvertantly reversed the length and width columns. We took them anyway but six months later (after a couple of episodes of working with expensive material that ended up as side drapes 96" wide and 30" long) I threw them all away. Your competition needs a standard timer. I can see why the difference between 59 seconds and 1.00 minutes looks dramatic.
