How many milliliters are in one fluid ounce?

Explanation:
Converting between volume units uses a fixed relationship between those units. In the United States, one fluid ounce is about 29.5735 milliliters, so rounding to two decimals gives 29.57 milliliters. That’s why this option is the best answer. The other values are off by significant factors: 3.785 milliliters is roughly a thousand times too small for a fluid ounce, 0.914 milliliters is about a quarter-teaspoon, not a fluid ounce, and 29.57 liters would be far too large (one fluid ounce is only about 0.02957 liters).
