I recommend against those using hybrids. You are asking for errors using them. You can't accurately measure from one side to the other and sometimes you have no choice but to read one way from one side and the other way from the other side which gives one measure in Imperial and the other in metric. I have maybe a half dozen tapes in all Imperial, 2 more that are only metric, several rules that are all Imperial, and a couple that are all metric. The metric rules are all brass, 1 metre long, and were used in the fabric industry for measuring cloth.
The worst thing to do is to convert from one to the other. Either work in Imperial or work in metric but converting back and forth doesn't work well.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
