One litre of water has a mass of almost exactly one kilogram when measured at its maximal density, which occurs at about 4 °C. It follows, therefore, that 1000th of a litre, known as one millilitre (1 mL), of water has a mass of about 1 g; 1000 litres of water has a mass of about 1000 kg (1 tonne or megagram). This relationship holds because ...
Example 1: If a block of solid stone weighs 3 kilograms on dry land and 2 kilogram when immersed in a tub of water, then it has displaced 1 kilogram of water. Since 1 liter of water weighs 1 kilogram (at 4 °C), it follows that the volume of the block is 1 liter and the density (mass/volume) of the stone is 3 kilograms/liter.
Seawater, or sea water, is water from a sea or ocean.On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na +
"The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10 −34 when expressed in the unit J s, which is equal to kg m 2 s −1, where the metre and the second are defined in terms of c and ∆ν Cs." [1] The mass of one litre of water at the temperature ...
A 1-euro coin weighs 7.5 g; [26] a Sacagawea US 1-dollar coin ... The mass of a litre of cold water is 1 kilogram. 1 millilitre of water occupies 1 cubic centimetre ...
"The majority of the adult body is water, up to 60% of your weight," says Schnoll-Sussman, adding that the average person's weight can fluctuate one to five pounds per day due to water.
1793: The grave (the precursor of the kilogram) was defined as the mass of 1 litre (dm 3) of water, which was determined to be 18841 grains. [ 11 ] 1795: the gram ( 1 / 1000 of a kilogram) was provisionally defined as the mass of one cubic centimetre of water at the melting point of ice.
The weight of just the container itself can for many practical purposes be considered negligible compared to the weight of the liquid it holds. Under this assumption, one can assume that the volume of a canister filled with water measured in liters will correspond to the same mass in kilograms.
