Fluid scruple


The scruple () is a small unit in the apothecaries' system, derived from the old Roman scrupulum (lit. "small pebble") unit (/).

The scruple is 124 ounce, 13 dram, or 20 grains. It is therefore equal to 1.2959782 grams. The Roman scruple was somewhat smaller, around 1.14 g.

The fluid scruple is 124 fluid ounce, 13 fluid dram, 20 minims, or 14 teaspoon, or 1 saltspoon. It is therefore equal to 1.23 milliliters.
