* 1 liter (L) is equal to 1000 milliliters (mL)

* 1 milliliter (mL) of water weighs approximately 1 gram (g)

However, ice cream is denser than water. This means 1 mL of ice cream will weigh slightly more than 1 gram. The exact weight will vary depending on the ingredients and fat content of the ice cream.

A reasonable estimate is that 1 liter of ice cream weighs approximately 1100 grams (1.1 kilograms).

Important Note: This is an approximation. To get a more precise weight, you'd need to consult the specific ice cream's nutrition label or weigh it yourself.
