The Metric System and Equivalents
Linear Measure
Liquid Measure
1 centiliter = 10 milliters = .34 fl. ounce
1 centimeter = 10 millimeters = .39 inch
1 deciliter = 10 centiliters = 3.38 fl. ounces
1 decimeter = 10 centimeters = 3.94 inches
1 liter = 10 deciliunces= 33.81 fl. o
1 meter = 10 decimeters = 39.37 inches
1 dekaliter = 10 liters = 2.64 gallons
1 dekameter = 10 meters = 32.8 feet
1 hectoliter = 10 dekaliters = 26.42 gallons
1 hectometer = 10 dekameters = 328.08 feet
1 kiloliter = 10 hectoliters = 264.18 gallons
1 kilometer = 10 hectometers = 3,280.8 feet
Square Measure
Weights
1 sq. centimeter = 100 sq. millimeters = .155 sq. inc
1 centigram = 10 milligrams = .15 grain
1 sq. decimeter = 100 sq. centimeters = 15.5 sq. inch
1 decigram = 10 centigrams = 1.54 grains
1 sq. meter (centare) = 100 sq. decimeters = 10.76 sq
1 gram = 10 decigram = .035 ounce
1 sq. dekameter (are) = 100 sq. meters = 1,076.4 sq.
1 decagram = 10 grams = .35 ounce
1 sq. hectometer (hectare) = 100 sq. dekameters = 2.4
1 hectogram = 10 decagrams = 3.52 ounces
1 sq. kilometer = 100 sq. hectometers = .386 sq. mile
1 kilogram = 10 hectograms = 2.2 pounds
1 quintal = 100 kilograms = 220.46 pounds
Cubic Measure
1 metric ton = 10 quintals = 1.1 short tons
1 cu. centimeter = 1000 cu. millimeters = .06 cu. inc
1 cu. decimeter = 1000 cu. centimeters = 61.02 cu. in
1 cu. meter = 1000 cu. decimeters = 35.31 cu. feet
