About the l to ml calculation
One liter is exactly 1,000 milliliters, so converting between them is a single multiplication. Enter any value above and the result updates as you type. The metric volume standard — one litre is exactly 1,000 cm³. The everyday unit for drinks, medicine doses and recipe liquids.
Formula
ml = L × 1,000
1 L = 1,000 ml
1 ml = 0.001 LWorked example
To convert 2 L, multiply by 1,000: 2 × 1,000 = 2,000 ml.
Frequently asked questions
How many milliliters are in a liter?
There are 1,000 milliliters in one liter. To convert any amount, multiply the number of liters by 1,000.
How do I convert milliliters back to liters?
Divide instead of multiplying, or equivalently multiply by 0.001. One milliliter is 0.001 liters.
Is this conversion exact?
Yes. Since the international agreement of 1959, the relationship between liters and milliliters is defined exactly rather than measured, so the only rounding here is in how many decimal places we show.
Where is each of these units used?
Liters: the metric volume standard — one litre is exactly 1,000 cm³. Milliliters: the everyday unit for drinks, medicine doses and recipe liquids.
