I grew up long after slide rules went out of fashion, but I really like them. And not only for their signaling value; I genuinely think they make working with specifically ratios easier.
For example if you have a recipe calling for 150 g of butter, but you want to use all of your 250 g, you can just align 150 and 250 on the slide rule, and then read off the correct amounts of the other ingredients, without ever touching the slide rule again. No multiplication performed.
I understand people don't use slide rules for more things, but I'm baffled they aren't considered standard kitchen equipment, in one shape or another.
