Both my fridge and freezer controls are labeled in deg C and you select the actual temperature you want. Which seems to me to be the only completely obvious way

Only works if the dial is calibrated. This very much not the case in the old days of mechanical thermostats. They were reliable and repeatable but not calibrated.

My parents have a new IKEA fridge, and it also has buttons in degrees Celsius. But as I mentioned below, until quite recently, the knob mechanically influenced a bimetallic strip which shut off the power when it became too cold. You cannot expect precise temperature control from this setup, and any calibration would likely be lost after some months of wear & tear. So printing exact temperature measurements on the knob would've given a false sense of precision. I also suspect that at least in some jurisdictions, some governmental body would require exact and lasting calibration if exact temperatures were printed on the knob. At least where I come from, thermometers used for food must be calibrated and approved by a governmental authority.

I've had both and both make sense. If there's no unit on display it's higher number = more cold (more power usage), without knowing how cold exactly. There is also a 0 usually, which can only mean off. Having 7 represent off would make no sense at all.

Big snowflake(s), medium snowflake, small snowflake on the dial. All embossed, of course. Arrow/tick mark on the panel. The bonus is this works in all temperature scales and language systems and probably includes most perception disabilities---blind, dyslexic, illiterate, etc. But I could still imagine a handful of people messing this one up. (Also, if the thing has an off mode... how do you mark and emboss that? A giant X? Well that looks like a snowflake, especially to your fingertip! A zero? A small horizontal line? Or, probably best, just a separate on/off switch...)

  > Big snowflake(s), medium snowflake, small snowflake on the dial. If you live in a snow-prone area you'll know that large snowflakes (which are actually clumps of flakes which happened to meet and merge on the way down) mean higher temperatures while small flakes equate to lower temperatures. So... Put it on the big flake to raise the temperature?
