Systems of Measurement: An in-depth look at the Imperial and Metric systems, including units of weight, volume, and their conversions, which are fundamental in pharmaceutical practices. ​
1. Imperial System
Avoirdupois system
Apothecaries system
Or
Troy system
2. Metric system

Avoirdupois system
Pound (lb) is taken as the standard of weight (mass).

1 pound (lb) = 16 ounce (oz)
1 pound (lb) = 7000 grains

16 oz = 7000 grains
1 oz = 7000/16 = 437.5 grains

Apothecaries system
Grain (gr) is taken as the standard of weight (mass).

1 pound (lb) = 12 ounce (oz)
1 pound (lb) = 5760 grains
12 oz = 5760 grains
1 oz = 5760/12 = 480 grains
1 oz = 8 drachms
1 drachms = 3 scruples
1 scruple = 20 grains
