Usually you would compare it to other instances of urban combat.

E.g. you might compare it to ukrainian battles that took place in cities, but you wouldn't compare it to ukrainian battles that took place in the middle of nowhere where no civilians were. https://en.wikipedia.org/wiki/Civilian_casualty_ratio has some things to compare against. Part of the problem is it is often hard to identify who is a civilian, and often different battles will categorize them differently. For example, in the iraq war us was accused of significantly undercounting civilian casualties. All this makes it hard to do direct comparisons.
