Scruple (unit)
From Infogalactic: the planetary knowledge core
The scruple (℈) is a small unit in the apothecaries' system,[1] derived from the old Roman scrupulum (lit. "small pebble") unit[2] (scrupulus/scrupulum).
Dry unit
The scruple is 1/24 ounce, 1/3 dram, or 20 grains.[1] It is therefore equal to 1.2959782 grams. The Roman scruple was somewhat smaller, around 1.14 g.
Fluid unit
The fluid scruple is 1/24 fluid ounce, 1/3 fluid dram, 20 minims, or 1/4 teaspoon. It is therefore equal to 1.23 milliliters.
