fixing definite weights for these volumes, necessarily different for dif- 

 ferent kinds of grain, and what is even worse, different in different 

 districts. However, custom in these matters is so powerful that it 

 will probably be long before such anomalies are abolished. 



The fundamental units and method of decimal multiples and sub- 

 multiples of the Metric system are doubtless sufficiently familiar 

 already to the reader. The connection between the metric units of 

 length, area, volume and weight and those of the British system will 

 therefore only be given here : 



Units of Length, 



1 metre = 39-3708 inches = 3-2809 feet = 1-0936 yards. 



1 kilometre = 3280-9 feet = 1093-63 yards = 0-62138 mile. 



or 



1 inch = 2-53995 centimetres. 



1 foot = 0-30479 metre. 



1 yard = 0-91438 metre. 



1 mile = 1-609315 kilometres.

Units of Area. 



= 1550 sq. inches = 10*764 sq. feet = 1-196 sq. yards. 

 = 1076-4 sq. feet = 119-6 sq. yards = 0'0247 acre. 



= 11960 sq. yards = 2-4711 acres. 



= 6-45137 sq. centimetres. 



= 9-290 sq. decimetres = 0-0929 sq. metre. 



= 0-8361 sq. metre. 



= 0-40467 hectare = 4046-7 sq. metres. 



Units of Volume. 

 - 061 cub. inch. : 

 61-028 cub. inches = 1-76 pints = 0'22 gallon. 



= 6102-8 cub. inches = 176 pints = 22 gallons = 

 2-7512 bushels. 



61028 cub. inches = 35-317 cub. feet = 1-308 cub. 

 yards = 220-09 gallons = 27*512 bushels. 



16-3862 cub. centimetres. 



28-3153 litres. 



567-93 cub. centimetres. 



4-54346 litres. 



0-7645 stere = 764-513 litres. 



36-3477 litres.
