Formula for calculating litres into kilgrams &, Copyright 1997-20014, OnlineConversion.com. Body fat has a specific density less than 1, so a person with more body fat will float. If it was water (specific gravity = 1), then 1 kg = 1 liter, and since 1 gallon 3,785 liter, that's. What Is the Densest Element on the Periodic Table? I think you're off by a factor of 1000 on that conversion of gallons to liters. How exactly does a turbine convert mechanical energy into electrical? The specific A hydrometer usually consists of a sealed hollow glass tube with a wider bottom portion for buoyancy, a ballast such as lead or mercury for stability, and a narrow stem with graduations for measuring. Since pure water is 1 g/cc or 1 kg/l, at 220 mg/l solids loading, a liter of your water should be 1.00022 kg. For example, if substance A has a specific volume of 0.358cm3/g and substanceB hasa specific volume of 0.374cm3/g, taking the inverse of each value will yield the density. Where as specific gravity is used in industries to measure the concentration of solutions. In other words, specific volume is inversely proportional to density. When using the SI or metric system, in order to calculate volume, mass is divided by the specific gravity or density; and, vice versa, to obtain mass, volume is multiplied by the specific gravity or density. The differences in intermolecular interactions, the density of substance can change at different rates compared to the density of water, that's why the specific gravity also changes with changing pressure and temperature. Volume = Mass Density. The equation may be used when dealing with gases, but the density of the gas (and its specific volume) may change dramatically with a slight increase or decrease in temperature. Remember, that you have to check the temperature of both the material and the reference (usually water) when quoting specific gravities. Specific gravity is the ratio of a material density with that of water at 4C ( which is 999.974 kg/m^3). As much steam as possible from engine exhaust gas + warm water? The difference between density and specific gravity is that density is an absolute quantity (mass per unit volume). kg = liter x density. Knowledge of density is important in the characterization and separation of materials. For example, in the column "HCl", you can see that hydrochloric
