CONVERSION TABLES

1. Common Metric Abbreviations.

kg = kilogram

m= meter

km = kilometer

dm = decimeter

MT = metric ton

cm = centimeter

mm = millimeter

2. Linear Measure.

l km= 0.6214 mi

l mi= 1,609.35 m

l m = 1.0936 yd

l yd= 0.9144 m

l m = 3.2808 ft

1 ft = 0.03048 m

1 m = 39.3700 in.

1 in. = 0.0254 m

l m= 10 dm = 100 cm = 1,000 mm

3. Surface Measure.

1 sq yd = 0.8361 sq m

l sqm= 10.764 sq ft

1 sq ft = 0.0929 sq m

l sqm= 1,550 sq in.

1 sq in. = 0.00064 sq m

4. Cubic Measure.

l cu m= 1.31 CU yd

l cu yd= 0.76455 cu m

1 cu ft = 0.02831 cu m

1 cu m = 35.30 cu ft

1 cu in. = 0.000016 cu m

1 cu m = 61,023 cu in.

5. Weight.

1 kg = 2.2046 lb

1 STON = 907.185 kg

1 MT = 1,000 kg

1 lb = 0.45359 kg

1 MT = 2,204.62 lb

l-in. x 6-in. x desired length = 2.5-cm x 15-cm

6. The following simplified conversion factors are

accurate to within 2 percent for quick computations:

x desired length.

6-in. x 8-in. x desired length = 15-cm x 20-cm

a. Inches to centimeters. Multiply in. by 10 and

x desired length.

divide by 4.

l-in. x 12-in. x desired length = 2.5-cm x 30-

b. Yards to meters. Multiply yd by 9 and divide

cm x desired length (length normally expressed in ft

by 10.

or m).

c . Miles to kilometers. Multiply mi by 8 and

b. Wire rope.

divide by 5.

3/8-in. dia = 9.5-mm dia

d. Pounds to kilograms. Multiply lb by 5 and

l/2-in. dia = 12.7-mm dia

divide by 11.

5/8-in. dia = 15.8-mm dia

Paragraph 7-37, FM 55-15 and paragraph 2-15, TM

3/4-in. dia = 19.O-mm dia

55-450-15 contain additional detailed conversion

7/8-in. dia = 22.2-mm dia

factors.

l-in. dia = 25.4-mm dia

7. The following conversions are provided for guid-

1 l/4-in. dia = 31.7-mm dia

ance when lumber, wire rope, or wire are procured

1 l/2-in dia = 38.1-mm dia

in areas that use the metric system. Lumber sizes

Round to the next higher whole mm of available

are rounded to the nearest 1/2 cm.

wire rope sizes.

a. Lumber.

c. Wire. No. 8 gauge annealed (1l/64-in dia) =

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

4.37-mm dia. Round as in b above.
