Metric Tables. 
The metric system of weights and measures having been adopted in 
the Photographic Office for convenience in keeping the store accounts, 
the following tables for the conversion of these measures to British 
and vice versa will be found useful. 
They have been based on the relative equivalents of the metric 
and British systems given in Schedule III- of the Weights and Mea- 
sures Act of 1878, and have been compiled from De la Rue’s Tables 
and other sources. 
As the metric system is now ordinarily used in scientific publi- 
cations, the scope of the tables has been extended so as to meet, as 
far as possible, the ordinary requirements of general and scientific 
reference. 
Use of the Tables. 
The number required to be converted, whether British or metric, 
may either be multiplied directly by the decimal fraction represent- 
ing the equivalent value of one unit of the required denomination, as 
found in the tables of equivalents or multipliers, according to the 
accuracy required ; or, it may be broken up into a series of constitu- 
ent parts in thousands, hundreds, tens, units and fractions, and the 
equivalents of the several amounts, as found from the tables of mul- 
tipliers, added together. In the latter case care must be taken to 
change the position of the decimal point as required for multiples or 
fractions of the unit.
