Ksubi to A.P.C. jeans size
The short answer
Ksubi 4 is A.P.C. 24 by the two brands' own charts.
Both brands publish the body waist each size is cut for, so every row matches a waist, not a tag.
On 9 sizes the charts land two or more sizes from the same label. Brands do not measure the body the same way, so on those rows treat the chart answer and the same label as the two ends of a range.
