How do I convert clothing size from cm to inches?
Clothing measurements follow standard body points: waist (measured around the navel), chest/bust (across the fullest part), hips (around the fullest point), and inseam (inner leg length). To convert any of these from cm to inches: divide by 2.54. Example: 82 cm waist ÷ 2.54 = 32.3 inches (a US size 32 waist). For European shoe sizes, the conversion is different — EU sizes are based on the foot length in cm multiplied by 1.5. US and UK shoe sizes use a different system unrelated to inches directly.
