choosing cm in scene > units > length does not have any effect when beveling an edge: pressing 1 results in 100 cm just like pressing 1 with meters results in 1m. the correct behavior should be to take the input at face value. 1 should be 1. When working with small objects and you need a 0.5cm bevel you currently need to put in .005
...or am I doing it wrong?
setting different unit Scale like 0.01 or 100 does not change the numeric interpretation either btw
