2. The conversion factors are: 1 gry  1/10 line , 1 line  1/12 inch and 1

point = 1/72inch. The factors imply that
gw gw gw gw gw gw gw gw




1 gry = (1/10)(1/12)(72 points) = 0.60 point.
gw gw gw gw gw gw gw




Thus, 1 gry2 = (0.60 point)2 = 0.36 point2, which means that 0.50

6. We make use of Table 1-6.

(a) We look at the first (―cahiz‖) column: 1 fanega is equivalent to what amount

of cahiz? We note from the already completed part of the table that 1 cahiz

equals a dozen12 fanega. Thus, 1 fanega = 1
gw gw gw cahiz, or 8.33  102 cahiz.
