Final answer:
To convert 15 fluid ounces to millimeters, we use the known conversion of 8 fluid ounces to 237 milliliters and scale it up, resulting in 444.375 millimeters for 15 ounces.
Step-by-step explanation:
The question 'About how many millimeters are in 15 fluid ounces?' involves a conversion from fluid ounces to milliliters, which can then easily be converted to millimeters. As we know there are approximately 237 milliliters in 8 fluid ounces, we can use a simple proportional calculation to find the equivalent for 15 ounces:
8 fluid ounces is to 237 milliliters as 15 fluid ounces is to x milliliters:
8 oz / 15 oz = 237 mL / x mL
Now, solving for x:
x = (15 oz × 237 mL) / 8 oz
x = 3555 mL / 8
x = 444.375 mL
Since there are 1,000 millimeters in one liter and therefore also 1 millimeter in 1 milliliter, 15 fluid ounces is equivalent to 444.375 millimeters (or milliliters).
