It depends on the pressure, but at one atmosphere it is 0.999 972 kilograms.
Water.
The mass of 1 liter of water is approximately 1 kilogram or 1000 grams.
1 liter of water has a mass of 1000 grams since there are 1000 cubic centimeters in a liter.
The weight of one liter of water is approximately 1 kilogram.
0.001
1 Liter or 1000 cubic centimeters of water at 4 degrees celsius has a mass of 1 kilogram. On earth, that mass weighs 2.205 pounds. (rounded) It has different weights in other places.
One liter of standard pure clean water at standard temperature and pressure has a mass of 1 kg.
1 liter of water at standard temperature and pressure (STP) would have a mass of approximately 1 kilogram.
The mass of 1 liter of water (H2O) is approximately 1 kilogram (kg) or 1000 grams (g).
The mass of 1 liter of water is approximately 1 kilogram. To convert this to newtons, you would multiply the mass in kilograms by the acceleration due to gravity, which is about 9.81 m/s^2. So, the weight of 1 liter of water is approximately 9.81 newtons.
The mass of 1.0 liter of water is approximately 1000 grams or 1 kilogram.
1 liter of H2O at 4 degrees C has a mass of exactly 1000 grams 1 liter of H2O at 4 degrees C has a mass of exactly 1 kilogram
