Metric System of Weights and Measures. 



I. LINEAR MEASURES. 

 X meter (m) = 10 decimeters (dm)= too centimeters (cm) = 1000 millimetei* 

 (mm) = .1 decameters (Dm) = .01 Hectometer (Hm) = .001 Kilometo 

 (Km) = .0001 Myriameler (Mm). 



I Mm = 10 Km = 100 Hm = 1000 Dm = 10,000 m; 

 I Km = 10 Hm = 100 Dm = 1,000 m; 

 I Hm = 10 Dm = 100 m; 

 I Dm = 10 m; 

 s m =s 10 dm =: 100 cm = 1000 mm ; 

 1 dm = 10 cm = 100 mm; 

 I cm = 10 mm. 



a. SURFACE MEASURES. 

 1 Are (a) = 100 square meters (sq. m.) = .01 hectare (haj ; 

 I Are = I sq. Dm. = 100 square m ; 

 I sq. Km = 100 Ha = 10,000 A = 1,000,000 sq. m J 

 I Ha = 100 A = 10,000 sq. m ; 

 I A = 100 sq. m. 



3. MEASURES OF CAPACITY. 

 I titer (l) = T cubic decimeter (cdm) = 1,000 cubic centimeters (c. c.) s 

 o.ooi cubic meter (cbm) = 10 deciliters (dl) = too centiliters (cl) = .o» 

 hectoliter (hi). 



I HI = 10 Dl = 100 1 = 1,000 dl = 10,000 cl ; 

 I Dl = 10 1 = 100 dl = 1,000 cl ; 



I 1 = 10 dl = lOO Cm 



4. WEIGHTS. 



f kilogram (kg) = 100 decagrams (Dg) = 1000 grams (g); 

 I gram = 10 decigrams (a^) — 100 centigrams (eg) = 1,000 milligrams (mgK 

 I ton = 1000 Kg = 100,000 Dg = 1,000,000 g ; 

 100 Kg = 10,000 Dg = 100,000 g j 

 I Kg = 100 Dg = 1,000 g. 



* I Imperial gallon = 277.274 cub. inches, or .16046 cub. foot; it equals 

 1.20032, or very nearly ij I'. S. liquid gallons, i cub. foot = 1728 cub. 

 inches = 7.48 U. S, liquid gallons = 6.43 U. S. dry gallons = 6.23 Imperial
