1gram = 27.334 grains.
A quarter stone is 14/4 = 3.5 pounds avoirdupois = 1587.6 g.

 

How do we interpret a "grain of dram"?

"Of" generally means "multiply" but here it must mean divide, yielding a dimensionless ratio..

But which way? Is it 27.334 or is it 0.0366?

 

One way, the answer could be 43395.4584g = 43.3954584kg

The other way it could be 58.1062g.

 

Or the answer could be good old 42.

 

Or, this whole thing could be ... a riddle.

 

Interesting question. :unsure:

Spoiler

Quarter is given to be not a portion of the measure or that which is measured, thus it is the measurement, and subsequently, the stone is the material being measured. A quarter is 28 pounds weight, which is approximately 196000 grains. A dram can be anything small, which in this case is the substance of stone. One grain is 1/196000 quarter of stone, and can be said to literally be a grain of sand.

Hint: quarter,stone,grain and dram are not S.I. units..

Are you saying they're not measurement units at all?
Or just that they are not SI (rationalized MKS) units of measurement in particular?
