How many liters are in 500 mL?

To determine how many liters are in 500 mL, it is important to understand the metric conversion between milliliters and liters. One liter is equivalent to 1,000 milliliters. Therefore, to convert milliliters to liters, one can divide the number of milliliters by 1,000.

In this case, you take 500 mL and divide it by 1,000:

500 mL ÷ 1,000 = 0.5 L.

The result shows that 500 mL is equal to 0.5 liters. This conversion is straightforward, as it directly applies the relationship between the two units of measurement. Consequently, the correct answer of 0.5 L accurately represents the conversion from 500 mL to liters.
