Q:

# How much does 1 liter of water weigh?

A:

A liter of water weighs 2.2 pounds at 39.2 degrees Fahrenheit. However, as the temperature changes, either higher or lower, the density decreases and so does the weight. This is due to the anomalous expansion of water.

With most substances, as they cool, their density increases because the activity of the atoms and molecules reduces and the substances contract. This changes the material from a gas to a liquid to a solid, which increases the weight of the substance. Water, however, actually decreases in density as it changes from a liquid to a solid. This is why ice floats on water.

One cup of water weighs approximately 8 ounces, which is equal to 225 grams. One cup holds 225 milliliters of water. The volume and weight of 1 cup of water are the same number under the metric system because the density of water is 1 gram per milliliter.
