- 20 grains ap = 1 scruple (exact)
- 3 scruples = 1 dram ap (exact)
- 8 dram ap = 1 oz ap (exact)
- 1 dram ap = 3.888 g

What is the mass of 1 scruple in grams?

Answer :

Final answer:

To find the mass of 1 scruple in grams, we divide the grams of 1 dram ap (3.888 g) by the number of scruples in a dram ap (3). Therefore, a scruple weighs approximately 1.296 grams.

Explanation:

To convert the mass of 1 scruple to grams, we must use the information provided in the question. Given that 1 scruple is exactly equal to 20 grains ap and 1 dram ap is equivalent to 3.888 grams, we can determine that 3 scruples equal to 1 dram ap.

Now, we divide 3.888 grams by 3 to find the mass of 1 scruple in grams. This gives us approximately 1.296 grams. Thus, in the system used by apothecaries, 1 scruple is approximately 1.296 grams.
