A-6.
The following simplified conversion factors are accurate to within 2 percent for quick computations:
a.
Inches to centimeters—Multiply in. by 10 and divide by 4.
b.
Yards to meters–Multiply yd by 9 and divide by 10.
c.
Miles to kilometers—Multiply mi by 8 and divide by 5.
d.
Pounds to kilograms-Multiply lb by 5 and divide by 11.
A-7.
The following conversions are provided for guidance when procuring lumber, wire rope, or wire in
areas that use the metric system. Lumber sizes are rounded off to the nearest 1/2 cm.
a. Lumber.
2-in x 4-in x desired length = 5-cm x 10-cm x desired length
1-in x 6-in x desired length = 2.5-cm x 15-cm x desired length
6-in x 8-in x desired length = 15-cm x 20-cm x desired length
1-in x 12-in x desired length = 2.5-cm x 30-cm x desired length
(length normally expressed in ft or m)
b. Wire Rope.
Round off to next higher whole mm of available wire rope sizes.
3/8-in. dia = 9.5-mm dia
1/2-in. dia = 12.7-mm dia
5/8-in. dia = 15.8-mm dia
3/4-in. dia = 19.0-mm dia
7/8-in. dia = 22.2-mm dia
1-in. dia = 25.4-mm dia
1 1/4-in. dia = 31.7-mm dia
1 1/2-in. dia = 38.1-mm dia
c.
Wire.
No. 8 gauge annealed (11/64-in. dia) = 4.37-mm dia. Round off to the next higher whole mm of
available wire rope sizes.
