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
l-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
l-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
l/2-in dia = 12.7-MM dia
5/8-in dia = 15.8-MM dia
3/4-in dia = 19.O-mm dia
7/8-in dia = 22.2-mm dia
l-in dia = 25.4-mm dia
l-1/4-in dia = 31.7-MM dia
l-1/2-in dia = 38.1-MM dia
Wire. No. 8 gauge annealed (11/64-in dia) = 4.37-mm
c.
