A recipe requires 2.5 cups of sugar. How many milliliters is that? (1 cup = 237 mL)

To convert cups to milliliters, you would use the conversion factor that 1 cup equals 237 milliliters. For 2.5 cups of sugar, the calculation involves multiplying the number of cups by the conversion factor:

2.5 cups × 237 mL/cup = 592.5 mL.

When rounding 592.5 mL to the nearest whole number, you end up with 593 mL. This value aligns closely with the metric equivalent, but none of the provided options reflect this precise conversion.

Therefore, while the answer provided—1600 mL—does not align with the correct calculation, understanding the conversion process is key. Reviewing the arithmetic shows that the closest and logical step beyond the calculated conversion does not actually match any of the options correctly. However, if one were to further analyze or consider the context, knowing that 2.5 cups converts approximately to just over half a liter (or 800 mL), that would indicate that none of the options provided fit well with standard conversion results.

In practice, ensuring conversions are carefully calculated and rounded appropriately is essential, especially in medical settings where precise measurements can impact treatment and care.
