The ounce avoirdupois contains 437°5 grains or 28-349 grammes. 
The pound avoirdupois contains 7000 grains or 453°59 grammes, there- 
fore 1 lb. of E.C. No. 3 will load 7999 = 212 cartridges containing the 
charge of 33 grains. 
The dram avoirdupois is the sixteenth part of the ounce of 437°5 grains. 
The dram, therefore, weighs 27°3 grains or 1°7718 grammes. Used in 
connection with the loading of cartridges the dram now refers to the volume 
occupied by ,'; oz. avoirdupois of water or of black powder. E.C. No. 3 
being lighter than black powder, 11 grains of the former occupy the bulk of 
1 dram or 27°3 grains of the latter, i.e. 33 grains of E. C. No. 3 are the same 
volume as 3 drams or 82 grains of black powder. 
The above measure must not be mistaken for the fluid dram, which 
contains 54°68 grains. 
The gramme equals 15'432 English grains; that is to say, I grain = 
‘0648 gramme. 
The metre equals 39°37 inches. There are, therefore, 25°9935 millimetres 
in an inch.
