This free conversion calculator will convert fluid drachms/drams (imperial) to gallons (US fluid, wine), i.e. fl dr (imp) to fl gal (US). Correct conversion between different measurement scales.

The formula is $V_{\text{fl gal (US)}} = \frac{56826125}{60566588544} V_{\text{fl dr (imp)}}$, where $V_{\text{fl dr (imp)}} = 15$.

Therefore, $V_{\text{fl gal (US)}} = \frac{284130625}{20188862848}$.

Answer: $15 \text{fl dr (imp)} = \frac{284130625}{20188862848} \text{fl gal (US)}\approx 0.01407363193951 \text{fl gal (US)}.$
