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.

Paragraph 7-37, FM 55-15, and paragraph 2-15, TM 55-450-15, contain additional detailed conversion factors.

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 nearest 1/2 cm.

a. Lumber.

2-in. x 4-in. x desired length = 5-cm x 1-cm x desired length

1-in. x 6-in. x desired length = 2.5-cm x 1-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.

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

Round off to next higher whole mm of available wire rope sizes.

c. Wire. No. 8 gauge annealed (11/64-in. dia) = 4-37-mm dia. Round off as in b above.
