1. 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 μm,
1km = 103 m = 103 m 106 μ m m = 109 μ m. The
given measurement is 1.0 km (two significant figures), which implies our result
should be written as 1.0 × 109 μm. (b) We calculate the number of microns in 1
centimeter. Since 1 cm = 10?2 m, 1cm = 10?2 m = 10?2 m 106 μ m m = 104 μ m. We
conclude that the fraction of one centimeter equal to 1.0 μm is 1.0 × 10?4. (c)
Since 1 yd = (3 ft)(0.3048 m/ft) = 0.9144 m,
1.0 yd = ( 0.91m ) 106 μ m m =
9.1 × 105 μ
m.

(a) Using the conversion factors 1 inch = 2.54 cm exactly and 6 picas = 1 inch,
we obtain 1 inch 6 picas ? 1.9 picas. 0.80 cm = ( 0.80 cm ) 2.54 cm 1 inch (b)
With 12 points = 1 pica, we have
0.80 cm = ( 0.80 cm ) 1 inch 2.54 cm 6 picas
1 inch 12 points ? 23 points. 1 pica
