Metric Weight and Measure Conversion
Linear	Weight	Area
10 millimeters [mm] = 1 centimeter 10 centimeters [cm] = 1 decimeter 10 decimeters [dm] = 1 meter 10 meters [m] = 1 dekameter [dam] 10 dekameters= 1 hectometer [hm] 10 hectometers = 1 kilometer [km]	10 milligrams [mg] = 1 centigram 10 centigrams [cg] = 1 decigram 10 decigrams [dg] = 1 gram [g] 10 grams = 1 dekagram [dag] 10 dekagrams= 1 hectogram [hg] 10 hectograms = 1 kilogram [kg] 1,000 kilograms = 1 metric ton [t]	100 sq. mm = 1 sq. centimeter 10,000 sq. centimeters = 1m² 100 sq. meters = 1 acres [a] 100 acres = 1 hectare [h] 100 hectares = 1 sq. kilometer

Linear Measure
1 inch = 25.4 millimeters [mm] 1 inch = 2.54 centimeters [cm] 1 foot= .3048 meter [m] 1 yard = .914 [m] 1 statute mile = 1.609 kilometers [km] 1 millimeter = .03937 inch 1 centimeter = .3937 inch 1 meter = 3.2808 feet 1 meter = 1.093 yards 1 kilometer = .6214 statute mile	Approximate conversions to metric measures
	When you know inches feet yards miles	Multiply by 2.5 30.00 0.9 1.6	To find centimeters centimeters meters kilometers

Area
1 sq. foot = 929.03 sq. centimeters [cm²] 1 sq. inch = 6.4516 cm² 1 sq. foot= .092 sq. meter [m²] 1 sq. yard = .836 m² 1 acre = 4,047 m² 1 sq. mile= 2,590 km²1 cm² = .155 sq. inch 1 m² = 10.8 sq. feet	Approximate conversions to metric measures
	When you know square inches square feet square yards square miles acres	Multiply by 6.5 0.09 0.8 2.6 0.4	To find square centimeters square meters square meters square kilometers hectares

Weight
1 ounce = 28.35 grams [g] 1 pound = .4536 kilogram [kg] 1 ton = .907 metric ton [t] 1 gram = .03527 ounce 1 kilogram = 2.2046 pounds 1 metric ton= 1.102 tons	Approximate conversions to metric measures
	When you know ounces pounds tons	Multiply by 28.00 0.45 0.9	To find grams kilograms tonnes

Temperature
32° Fahrenheit = 0° Celsius F° = 9/5 C° + 32° 17.8° Celsius = 0° Fahrenheit C° = (F° -32°) x 5/9	Approximate conversions to metric measures
	One Fahrenheit degree is 5/9 of a celsius degree. To Celsius: subtract 32, multiply by 5 and divide by 9. From Celsius to Fahrenheit: multiply by 9, divide by 5, and add 32.
