Fluid drachms/drams (imperial) to fluid drachms/drams (US)

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

The formula is $V_{\text{fl dr (US)}} = \frac{454609000}{473176473} V_{\text{fl dr (imp)}}$, where $V_{\text{fl dr (imp)}} = 15$.

Therefore, $V_{\text{fl dr (US)}} = \frac{2273045000}{157725491}$.

Answer: $15 \text{fl dr (imp)} = \frac{2273045000}{157725491} \text{fl dr (US)}\approx 14.4113991060583 \text{fl dr (US)}.$
