How to Convert Milliliters to Liters (and Vice Versa)
The conversion process is straightforward, involving simple multiplication or division by 1000. Let’s outline the steps involved:
Converting Milliliters to Liters
To convert milliliters to liters, divide the number of milliliters by 1000. This is because there are 1000 milliliters in every liter.
Formula: Liters = Milliliters / 1000
Example: Convert 750 ml to liters.
Liters = 750 ml / 1000 = 0.75 L
Therefore, 750 ml is equal to 0.75 liters.
Converting Liters to Milliliters
To convert liters to milliliters, multiply the number of liters by 1000. This is because there are 1000 milliliters in every liter.
Formula: Milliliters = Liters * 1000
Example: Convert 2.5 liters to milliliters.
Milliliters = 2.5 L * 1000 = 2500 ml
Therefore, 2.5 liters is equal to 2500 ml.
