Fluid drachms/drams (US) to teaspoons (US customary)

This free conversion calculator will convert fluid drachms (US) to teaspoons (US customary), i.e. fl dr (US) to tsp (US). Correct conversion between different measurement scales.

The formula is $V_{\text{tsp (US)}} = \frac{3}{4} V_{\text{fl dr (US)}}$, where $V_{\text{fl dr (US)}} = 15$.

Therefore, $V_{\text{tsp (US)}} = \frac{45}{4}$.

Answer: $15 \text{fl dr (US)} = \frac{45}{4} \text{tsp (US)} = 11.25 \text{tsp (US)}$.
