FRAME 4-18.
Solution to
In the U.S. system, the normal units of length measurement are the inch,
Frame 4-17.
foot, yard, and mile. These units were defined in Frame 4-13. The
approximate equivalents of these units in the metric system are given
37 mm = 3.7 cm =
below. More exact conversion figures are given in the appendix.
0.037m = 0.000037km
1 inch = 2.5 cm = 25 mm
250 mm = 25 cm =
0.25 m = 0.00025 km
1 foot = 30 cm = 0.3 m
1200 mm = 120 cm =
1 yard = 91 cm = 0.91 m
1.2 m = 0.0012 km
1 mile = 1.6 km
3,300,000 mm =
330,000 cm =
3,300 m = 3.3 km

a length measurement from the U.S. system to the metric system. The
information below will help you to change lengths from the metric system
75 cm or 3/4 (0.75) m
to the U.S. system. More exact conversion figures are given in the
appendix.
(using the conversion
formulas shown in Frame
1 mm = 0.04 inches
4-18)
1 cm = 0.4 inches = 0.03 feet
1 m = 1.1 yards = 3.3 feet = 39 inches
1 km = 0.62 (about 5/8) miles = 1094 yards = 3281 feet
