Tea-Rex is on a distinguished road
well, since i grew up in metric units, i aproach it the other way ...
1'=304.8mm=0.3048 m (btw, 1/0.3048=3.28084)
devide metres through 3, multiply with 10 (really just moving the decimal point) and cut an inch for every 5 feet ... for more precission add 1/2 inch for every 40 feet (or actually, 1/8" per 10 feet)

15m /3=5
5*10 = 50
50'-10"=49'2"[+1/2"]

indeed, 15m/0.3048=49.2126'=49'2.55"
