.. however ... beware ... there exist traps for young players.
Many decades ago I purchased a set of whatever secondhand kit it was .. which included a nice, if old, cloth tape of prodigious length.
Quick cal check - foot to foot - against a steel tape was fine. Just a pity that I didn't look at it a bit closer ...
First time I used this - without actually having had a close look at the device (I mean .. a tape measure is just a tape measure ... surely ?) - to run an aircraft reweigh I came up with some strange answers ... reweigh ... same strange answers ...
Eventually twigged to the fact that the tape was in feet, tenths and hundredths of feet ... only ever seen the one. Once the problem was identified the solution was trivial .. still, an interesting "gotcha".
