1 cup = 1 cup
7 pints = 14 cups   (1 pint :2 cups)
9 quarts = 36 cups  (1 quart: 4 cups)
-------------------------
51 cups.

Convert 51 to base 2.

Divide 51 by 2 repeatedly and observe remainder.

51/2  = 25 r 1
25/2  = 12 r 1
12/2  = 6  r 0
6/2   = 3  r 0
3/2   = 1  r 1
1/2   = 0  r 1

Read resulting remainders from bottom to top.  110011(base 2) cups.
