Clothing measurements aren't even consistent between countries, there's effectively no standard. If where you live measurements are based on something sensible, that's pretty lucky.
The XS/S/M/L/XL sizes of course differ for men vs women, and EU sizes which to me have always seemed like an arbitrary number do too. But usually individual clothing manufacturers provide precise measurements to translate into the generic sizes, because of course that's not consistent either. It's a complete shitshow, but ultimately gender size conversions aren't going to help you with the manufacturer differences anyway. But those really should be more easily available inside clothing stores
