It depends on what temperature, because the density of water is quite responsive to temperature. But at 4 degrees Celcius, a cubic centimeter (1 mL) of water weighs a gram. This was actually how a gram was originally defined, and it is the greatest density of water, which expands at higher and lower temperatures.

To be precise, you have to tell me where you are for me to tell you how much water "weighs".
Water has a MASS of 1 liter = 1 kilogram at 4°C. What that translates into on Earth is "a pint a pound the world around", so a gallon weighs ~ 8 pounds ON EARTH. If I were to weigh that same gallon of water on the moon, my Earth-calibrated scale would measure 0.5 pounds for the weight -- even though both samples have the *same mass*.

A liter weighs 1 kg.
The two below mention temperature, something I neglected. Props to them.

It depends by the temperature.
The density is max at 4 °C:
0,999972 kg/liter

This old saying may help you:
A pint a pound, the world around.
