The correct answer is: $1.8927\text{ L}$ (using US fluid ounces)
Explanation
Assuming you mean US fluid ounces (common in recipes and US measurements), 1 US fl oz = $29.5735295625\text{ mL}=0.0295735295625\text{ L}$. Multiply 64 by that conversion factor and convert milliliters to liters.
Steps:
- Conversion factor: $1\text{ US fl oz}=0.0295735295625\text{ L}$
- Multiply: $64\times0.0295735295625=1.892705892\text{ L}$
- Round to a convenient number of digits: $1.8927\text{ L}\approx1.893\text{ L}$
Therefore, 64 US fluid ounces ≈ $1.8927\text{ L}$ (about $1.893\text{ L}$).
Note: If you meant 64 Imperial fluid ounces (UK), use $1\text{ imp fl oz}=0.0284130625\text{ L}$, giving $64\times0.0284130625=1.8184\text{ L}$. If you meant 64 ounces by weight, you must specify the substance (density) to convert to liters.
