This will be best illustrated by examples. 
Supposing it be desired to find the equivalent of 645' 15 litres in 
pints. 
By the first method 645-15 is multiplied by the equivalent of 1 
litre in pints = 1-76077, giving a product of 1135-961. 
By the second method the total number of litres may be broken 
up as follows : — 
600-00 litres = 1056-462 pints.

Adding together the equivalents of the constituent parts in pints 
the same total is obtained. 
Conversely : — Supposing it be desired to find the equivalent of 3 
cvvt. 25Tb 14I ounces in kilogrammes, the whole sum may be reduced 
to ounces and multiplied by "02835, the equivalent of 1 ounce in 
kilogrammes, thus : — 
5790 - 5oz x -02835 = 164-161 kilos. 
But in this case the result will be more accurately and simply 
obtained by finding the metric equivalents of the separate items of 
British measure from the tables, and adding them together, thus :■ — 
3 cwt. 
= 
152-407 kilos.

In some cases the first method will be the simplest and in others 
the second. The tables of multipliers show only 3 places of decimals, 
and therefore, if greater accuracy be required, especially in the first 
method, a longer fraction of at least 5 places of decimals should be 
taken from the tables of equivalents. 
Note. — The value of the metre given in the Table I = 39'37°79 inches, in vacuo, at Sea-level, 
was determined by Captain Kater in 1818, the temperature of the standard yard being 6a° F. and 
of the metre 32 0 F. It has since then been recognised as the authoritative legal equivalent of the metre in 
British measure and still remains so. 
In the course of his comparison of the standards of length of various countries, made at the Ordnance 
Survey Office, Southampton, in 1865, Captain A. R. Clarke* R.E., determined the true length of the legal 
equivalent of the metre under the above conditions of temperature to be 1*09362311 yards = 3*28086933 feet 
= 39*37043196 inches (see ‘‘Comparison of the Standards of Length,” p. 280).
