TABLE 
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
