What is the equivalent of 1 liter in milliliters?

One liter is equivalent to 1000 milliliters. This is based on the metric system, where the prefix "milli-" indicates a factor of one-thousandth. Therefore, when converting liters to milliliters, you multiply the number of liters by 1000. Consequently, 1 liter × 1000 = 1000 milliliters. This fundamental conversion is critical in various healthcare settings, including pharmacies, where precise measurements of liquids are often required. Understanding this conversion helps ensure medication doses are accurately prepared and administered.
