2. The conversion factors are: 1 gry 1/10 line , 1 line 1/12 i nch and 1 point
= 1/72 inch. The factors imply that
1 gry = (1/10)(1/12)(72 points) = 0.60 point.
Thus, 1 gry2 = (0.60 point)2 = 0.36 point2, which means that 0.50 gry 2 = 0.18 point 2 .
3. The metric prefixes (micro, pico, nano, …) are given for ready reference on the
inside front cover of the textbook (see also Table 1–2).
(a) Since 1 km = 1 103 m and 1 m = 1 106 m,
1km 103 m 103 m m.

m 10
109
The given measurement is 1.0 km (two significant figures), which implies our
result should be written as 1.0 109 m.

(b) We calculate the number of microns in 1 centimeter. Since 1 cm = 10 m,

104 m.
We conclude that the fraction of one centimeter equal to 1.0 m is 1.0

5. Given that 1 201.168 m , 1 rod and 1 chain 20.117 m , we
furlong 5.0292 m find
the relevant conversion factors to be
1 rod
1.0 furlong 201.168 m 40 rods,
(201.168 m ) 5.0292 m
and
1 chain
1.0 furlong 201.168 m 10 chains .
(201.168 m ) 20.117 m
Note the cancellation of m (meters), the unwanted unit. Using the given
conversion factors, we find
(a) the distance d in rods to be
40 rods
d 4.0 furlongs 4.0 furlongs 160 rods,
1 furlong
(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
dozen fanega.
Thus, 1 fanega =12 cahiz, or 8.33 10 2 cahiz. Similarly, “1 cahiz = 48 cuartilla”
