TABLE 
FOE CONVEETING MILLIMETEES INTO ENGLISH 
INCHES AND DECIMALS. 
EXPLANATION. 
The table herewith given shows the equivalents in Eng- 
lish inches, and decimals thereof, of every tenth of a milli- 
metre, from 1.0 to 100.9. From 100 to 1,000 millimetres 
may be reduced to inches and decimals by multiplying the 
corresponding figures of this table by ten ; that is, by mov- 
ing 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 72.7 millimetres to English inches : Find 
in the vertical column to the left the figures 72; then 
follow the horizontal line to the column headed .7. The 
number found there (or, what would be sufficient for all 
practical purposes, 2.86) is the equivalent of 72.7 millimetres 
in English inches. 
(2) To reduce 605 millimetres to English inches, find 
in the vertical column to the left 60, then follow the line 
to the column headed .5, where will be found 2.3819 ; move 
the point to the right, and you will have as the equivalent 
of 605 millimetres 23.819 (or, what is essentially the same, 
23.82) inches. 
(3) To reduce 1930 millimetres, find in the same way 
the equivalent of 19.3, which is 0.7599 ; move the point two 
places to the right, and 75.99 results, which expresses ex- 
actly the equivalent of 1930 millimetres in English inches.
