In one litre bottle of mercury contents 13.6 kg. So its Mass of Mercury in kg of one Litre Mercury Source- PinterestĮxample – 3 For Mercury, Relative density is 13.5 and density is 13.6 kg/ Litre. In one litre bottle of ghee contents 0.905 kg. Similarly we may find the relation of other material if we know its relative density Note Due to less density than water, ghee floats in water. Įxample – 2 For Ghee, Relative density is 0.905 and density is 0.905 kg/ Litre. In one litre bottle of Water contents 1 kg. So its one Kilogram is just equal to one Litre at 4 ☌. If the relative density is exactly 1 then the densities are equal that is, equal volumes of the two substances have the same mass.Įxample-1 For Water, relative density is 1. If greater than 1 then it is denser than the given substance. If a substance’s relative density is less than 1 then it is less dense than the given substance. Specific gravity is nearly always measured with respect to water at 4 ☌. Īs per the Wikipedia, Relative density of Specific gravity is the ratio of the density of a substance to the density of a given reference material. From 1901 to 1964 the litre was defined as the volume of one kilogram of pure water at 4☌ (39.2 ☏) and standard atmospheric pressure in 1964 the original, present value was reinstated. Litre (l), also spelled liter, unit of volume in the metric system, equal to one cubic decimetre (0.001 cubic metre). A liter is thus equal to both 1000 cm 3 (10 cm × 10 cm × 10 cm) and to 1 dm 3. This very large volume is not very convenient for typical use in a chemistry laboratory. A liter (L) is the volume of a cube that measures 10 cm (1 dm) on each side. The SI unit of volume is the cubic meter (m 3 ), which is the volume occupied by a cube that measures 1 m on each side. Instead, liquids vary in their density, or the amount of mass per unit volume. The conversion from liters to kilograms would therefore be very simple if all substances were identical to water. the litre is defined in terms of kilogram in 1795. In 1901, the General Conference on Weights and Measures defined 1 liter as the volume of exactly 1 kilogram of water at room temperature. A litre is a unit of volume, or space while a kilogram is a unit of mass, representing a given quantity of matter. In the metric system of SI( International System) units, liters and kilograms are both important units of measurement of any substance. If less mass of one substance in comparison of another substance is packed in a particular volume then its density will be less than given object and vice versa. Density shows the packing of mass in the volume. The mass of objects may equal or greater or lesser than its volume. Difference in the density occurs due to different mass and volume ratio. While the density of the fluid is less than solids. In the language of science, the density of every object is equal to its mass divided by the volume. Because the layman man knows that 1 kg of water is equal to 1 liter of water, which is also scientifically correct. Because only 905 grams of ghee comes in 1 liter of ghee, but the price is taken equal to 1 kg of ghee, similarly the same happens in other substances. This confusion arises for business benefits. When we go to the market, we ask the shopkeeper to give 1 kg of ghee but he gives 1 litre of ghee. People generally think that 1 kg of liquid is equal to 1 litre of liquid. 1 Litre ghee is equal to 905 gram.Įxample 3 -One litre of Cooking Oil is equal to 910 gram. You will be surprised that the volume and mass of all liquids are not the same.Įxample-1 One litre of ice cream is equal to 540 gram.Įxample 2 -One litre of ghee is not equal to 1 kg of ghee. Now the question arises what happens if the fluid is also measured as mass. Such as 2 liters of milk, 5 liters of water, 2 liters of petrol etc. So we measure amount of the fluid on the basis of its volume. Therefore, as we place the fluid in the vessel, it takes its shape. Such as 5 kg sugar, 10 kg flour, 2 kg rice etc.īut the fluid does not have a fixed shape. Therefore, in a normal routine, we express the amount of a solid object in its mass. As we know that a solid object has a fixed size and a fixed volume.
