Measures of Length
10 millimeters (mm) = 1 centimeter (cm)
10 centimeters = 1 decimeter (dm)
10 decimeters = 1 meter (m)
1000 meter = 1 kilometer (km)

Measures of Weight
10 milligrams (mg)= 1 centigram (cg)
10 centigrams = 1 decigram (dg)
10 decigrams = 1 gram (g)
10 grams = 1 decagram (Dg)
10 decagrams = 1 hectogram (Hg)
10 hectograms = 1 Kilogram (Kg)
1000 kilograms = 1 (metric) ton (T)

Surveyor’s Square Measure
100 square meters (m.2 ) = 1 are (ar)
100 acres = 1 hectare (har)
100 hectares = 1 sq. kilometer

Square Measure
100 sq. millimeters = 1 sq. centimeter
100 sq. centimeters = 1 sq. decimeter
100 sq. decimeters = 1 sq. meter

Cubic Measure
1000 cu. millimeters  = 1 cu. centimeter
1000 cu. centimeters = 1 cu. decimeter
1000 cu. decimeters = 1 cu. meter

Dry and Liquid Measure
10 milliliters (ml) = 1 centiliter (cl)
10 centiliters = 1 deciliter (dl)
10 deciliters = 1 liter (l)
100 liters = 1 hectoliter (H.)
1 liter = 1 cubic decimeter = the volume of 1 kilogram of pure water at a temperature of 39.2 degrees F
