Studied height so much that I memorized the conversion

[Growth Plate]

in x 2.54 but you could just
180 = 5'11" obv
+ 3 = 183 6ft
+2 = 185 6'1"
+3 = 188 6'2"
+2 = 190 6'3"
For half inches, it's the number you add to get to the next inch divided by 2 obv and the same concept for thirds and quarters obv
It always goes in this pattern, probably common kindergarten tier knowledge especially on this worldwide forum but I'm from the US where we only use ft and inches obv
