How many milliliters are equivalent to 1 liter?

To understand why 1 liter is equivalent to 1,000 milliliters, it helps to know the metric system's conversion factors. In the metric system, the liter (L) and milliliter (mL) are both units of volume. Specifically, 1 liter is defined as 1,000 milliliters, making it a straightforward conversion.

This relationship is based on the prefix "milli," which denotes a factor of one-thousandth (1/1,000). Therefore, when converting liters to milliliters, one simply multiplies by 1,000. So, if you have 1 liter, you multiply it by 1,000 to find the equivalent volume in milliliters. That leads us directly to the conclusion that 1 liter equals 1,000 milliliters, reaffirming the correct answer.
