There's a digital scale by MyWeigh cald the KD8000 that has an interesting feature for some bakers. It lets you weigh in baker's percentages. So if you have a bread recipe in that format, you can weigh your 100% ingredient, shift it into % mode, and then weigh everything else in terms of percent.
I know about this because very randomly I helped them design it. When I was getting tech support for a different scale model, I was in the middle of learning to make bread with a pile of professional cookbooks, and asked them if they made a scale that worked with percentages. They said no, but that if I sketched them what the interface would be like, they'd send me a free scale. I did and they did. Years later, when I needed a new scale, I found the one I designed and bought it.
Punch line: I've only used the baker's % feature once in the 10 years I've had the thing. Not actually useful to me. But maybe useful to someone who works with those formulas all day?
It's a little over $50 on Amazon. Capacity is 8000g (not 8000 lbs, as the amazon listing says ... )
