How it works
The milliliter is a metric unit of volume, defined as exactly one-thousandth of a liter:
1 Liter (L) = 1,000 Milliliters (mL)
Formula: mL = Liters × 1,000
Converting Liters to Milliliters (L to mL)
Since 1 liter contains exactly 1,000 milliliters, you can convert from L to mL by multiplying by 1,000.
Example: 3.5 liters = 3.5 × 1,000 = 3,500 mL
To convert from mL to L, divide the value in milliliters by 1,000.
Example: 750 mL = 750 ÷ 1,000 = 0.75 L
