Easy way to think about miles and feet (for me):
440 yards in a quarter mile X 4 quarters in a mile divided X 3 ft in a yard = 5,280 ft in a mile. From there it is easy.
BTW I only remember the 440 yds/ qtr, everything else I need to calculate.

|distance (in metres) div by gain (in metres). eg 250/4500 x 100 = 5.5%.
I'm glad we have use metric I would never have gotten through school with the imperial system :-)
