6'4" (76 inches) = 193 cm.
I've been 6'5" before (barefoot), but that was after 3 solid months of standing & sitting with the best possible posture at all times (during USMC boot camp). I could probably do it again if I really wanted to, but no thanks. I consider myself a good height. Not so tall, that eveyone can't stop staring, but, also always tall enough to see over (just about) everyone else's heads in a crowd.
