Units of Length

 

 

10 millimeters (mm)

= 1 centimeter (cm)

10 centimeters

= 1 decimeter (dm) = 100 millimeters

10 decimeters

= 1 meter (m) = 1000 millimeters

10 meters

= 1 dekameter (dam)

10 dekameters

= 1 hectometer (hm) = 100 meters

10 hectometers

= 1 kilometer (km) = 1000 meters

 

Units of Area

 

 

100 square millimeters (mm2)

= 1 square centimeter (cm2)

100 square centimeters

= 1 square decimeter (dm2)

100 square decimeters

= 1 square meter (m2)

100 square meters

= 1 square dekameter (dam2) = 1 are

100 square dekameters

= 1 square hectometer (hm2) = 1 hectare (ha)

100 square hectometers

= 1 square kilometer (km2)

 

Units of Liquid Volume

 

 

10 milliliters (mL)

= 1 centiliter (cL)

10 centiliters

= 1 deciliter (dL) = 100 milliliters

10 deciliters

= 1 liter1 = 1000 milliliters

10 liters

= 1 dekaliter (daL)

10 dekaliters

= 1 hectoliter (hL) = 100 liters

10 hectoliters

= 1 kiloliter (kL) = 1000 liters

 

Units of Volume

 

 

1000 cubic millimeters (mm3)

= 1 cubic centimeter (cm3)

1000 cubic centimeters

= 1 cubic decimeter (dm3)

 

= 1 000 000 cubic millimeters

1000 cubic decimeters

= 1 cubic meter (m3)

 

= 1 000 000 cubic centimeters

 

= 1 000 000 000 cubic millimeters

 

Units of Mass

 

 

10 milligrams (mg)

= 1 centigram (cg)

10 centigrams

= 1 decigram (dg) = 100 milligrams

10 decigrams

= 1 gram (g) = 1000 milligrams

10 grams

= 1 dekagram (dag)

10 dekagrams

= 1 hectogram (hg) = 100 grams

10 hectograms

= 1 kilogram (kg) = 1000 grams

1000 kilograms

= 1 megagram (Mg) or 1 metric ton(t)

 

2. TABLES OF U.S. UNITS OF MEASUREMENT2

 

In these tables where foot or mile is underlined, it is survey foot or U.S. statute mile rather than international foot or mile that is meant.

 

Units of Length

 

 

12 inches (in)

= 1 foot (ft)

3 feet

= 1 yard (yd)

16-1/2 feet

= 1 rod (rd), pole, or perch

40 rods

= 1 furlong (fur) = 660 feet

8 furlongs

= 1 U.S. statute mile (mi) = 5280 feet

1852 meters

= 6076.115 49 feet (approximately)

 

= 1 international nautical mile

 

Units of Area3

 

 

144 square inches (in2)

= 1 square foot (ft2)

9 square feet

= 1 square yard (yd2)

 

= 1296 square inches

272-1/4 square feet

= 1 square rod (sq rd)

160 square rods

= 1 acre = 43 560 square feet

640 acre

= 1 square mile (mi2)

1 mile square

= 1 section of land

6 miles square

= 1 township

 

= 36 sections = 36 square miles

 

Units of Volume3

 

 

1728 cubic inches (in3)

= 1 cubic foot (ft3)

27 cubic feet

= 1 cubic yard (yd3)
