Similarly I am on iOS 16.2 and have measurement system set to metric, my region to Norway, and my main preferred language to English.

I see the following: 0,24 l | 23,66 cl | 236,59 ml | 236,59 cm^3

It’s using comma as decimal because the number format is set as 1 234 567,89 as is default for region Norway.

It’s weird that mine shows the symbol for litres as a lowercase L and not as an uppercase L though.
