TAELE 



FOR CONVERTING ENGLISH INCHES AND 

 DECIMALS INTO MILLIMETRES. 



EXPLANATION. 



The accompanying table shows the equivalent of every 

 hundredth of an English inch, from 0.01 to 10.09 inches, in 

 millimetres and decimals thereof. From 10 to 100 inches 

 may be reduced to millimetres and decimals by multiplying 

 the corresponding figures of this table by 10 ; that is, by 

 moving the point in the column of inches one place to the 

 right. In a similar way, if multiplying by 100, move the 

 point two places to the right. For example : 



(1) To reduce 4.36 inches to millimetres : Find in the 

 first or left-hand column the figures 4.3 ; then follow the 

 horizontal line toward the right to the column headed .06. 

 The number found there, 110.74 (or, what would be suffi- 

 ciently near for all practical purposes, 111), is the equiva- 

 lent of 4.36 inches in millimetres. 



(2) To reduce 15.77 inches to millimetres : Find in the 

 first or left-hand column the figures 1.5; then follow the 

 horizontal line toward the right to the column headed .07, 

 where will be found the figures 39.88 ; now move the point 

 one place to the right, and you have 398.8, which is the 

 exact equivalent of 15.70 inches ; now find the equivalent 

 of 0.07 inches, which is 1.78 millimetres, and add to the
