One liter is equal to 1,000 milliliters. This is a standard conversion in the metric system, where the prefix ‘milli’ signifies a factor of one-thousandth. Therefore, if you have a liter of liquid, you can convert it to milliliters by multiplying by 1,000.
This relationship is particularly useful in cooking, science experiments, and other activities that require precise measurements. For example, if a recipe calls for 2 liters of water, you can easily convert that to milliliters by calculating 2 times 1,000, which equals 2,000 milliliters.
