Cubic inches to fluid drachms/drams (US)

This free conversion calculator will convert cubic inches to fluid drachms (US), i.e. in^3 to fl dr (US), cu in to fl dr (US). Correct conversion between different measurement scales.

The formula is $V_{\text{fl dr (US)}} = \frac{1024}{231} V_{in^3}$, where $V_{in^3} = 15$.

Therefore, $V_{\text{fl dr (US)}} = \frac{5120}{77}$.

Answer: $15 in^{3} = \frac{5120}{77} \text{fl dr (US)}\approx 66.4935064935065 \text{fl dr (US)}$.
