Non-Frequently Asked Questions About Stones to Drams

Questions nobody should ask - but someone did.

It is 14 x 256 = 14 x 2⁸, which combines the stone's 14-pound definition with the binary power structure of the ounce-dram hierarchy. The number reveals the hidden connection between the stone's decimal factor (14) and the imperial system's binary factors (16 x 16 = 256).
A sneeze expels about 0.01 to 0.02 grams of material, roughly 0.006 to 0.011 drams. At 3,584 drams per stone, your sneeze represents about 0.000003 stone of weight loss, which no bathroom scale on Earth could detect. Sneezing is not a viable weight-loss strategy.
Profoundly. 'I've lost 3,584 drams' would replace 'I've lost a stone,' and weight-loss celebrations would be mathematically grander but conversationally unwieldy. Pubs would need to update their 'I lost a stone!' boards to 'I lost 3,584 drams!' which sounds like a fantasy role-playing game achievement rather than a health milestone.
