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: $$$15 in^{3} = \frac{5120}{77} \text{fl dr (US)}\approx 66.493506493506494 \text{fl dr (US)}.$$$
