Tables for Metric Measurements & Conversions

Part 1: Measurements

Linear Measure
10 millimeters (mm) =    1 centimeter (cm)    
10 centimeters =    1 decimeter (dm)    = 100 millimeters
10 decimeters =    1 meter (m)    = 1,000 millimeters
10 meters =    1 dekameter (dam)    
10 dekameters =    1 hectometer (hm)    = 100 meters
10 hectometers =    1 kilometer (km)    = 1,000 meters

Area Measure
100 square millimeters (mm2) =    1 sq centimeter (cm2)
10,000 square centimeters =    1 sq meter (m2)
=    1,000,000 sq millimeters
100 square meters =    1 are (a)
100 ares =    1 hectare (ha)
=    10,000 sq meters
100 hectares =    1 sq kilometer (km2)
=    1,000,000 sq meters

Volume Measure
10 milliliters (ml) =    1 centiliter (cl)    
10 centiliters =    1 deciliter (dl)    = 100 milliliters
10 deciliters =    1 liter (l)    = 1,000 milliliters
10 liters =    1 dekaliter (dal)    
10 dekaliters =    1 hectoliter (hl)    = 100 liters
10 hectoliters =    1 kiloliter (kl)    = 1,000 liters

Cubic Measure
1,000 cubic millimeters (mm3) =    1 cu centimeter (cm3)
1,000 cubic centimeters =    1 cu decimeter (dm3)
=    1,000,000 cu millimeters
1,000 cubic decimeters =    1 cu meter (m3)
=    1 stere
=    1,000,000 cu centimeters
=    1,000,000,000 cu millimeters

Weight
10 milligrams (mg) =    1 centigram (cg)    
10 centigrams =    1 decigram (dg)    = 100 milligrams
10 decigrams =    1 gram (g)    = 1,000 milligrams
10 grams =    1 dekagram (dag)    
10 dekagrams =    1 hectogram (hg)    = 100 grams
10 hectograms =    1 kilogram (kg)    = 1,000 grams
1,000 kilograms =    1 metric ton (t)
