Welcome to liter to kg, our website made for helping you with the liters to kilograms conversion. Throughout this website we use the American spelling variant liter, as opposed to litre, the international writing. Along the same lines we use kilogram, instead of kilogramme. The liter is a unit of volume; the unit symbol is l or L, but you sometimes come across the abbreviation ltr. In turn, the kilogram is the International System of Unit’s base unit of mass; the symbol is kg. Therefore, L to kg is a volume to mass conversion.
Liters to Kilograms
The link between the quantity volume (V) and the property mass (m) is called density. The volumetric mass density D is defined as the quotient m / V, which, for a given substance, varies depending on temperature and pressure conditions. On top of that, different materials generally have different densities.
Because liters to kilograms is a volume to mass conversion, the substance-specific density connects the mass and volume, in function of pressure and temperature, as can be seen in the formula below.
Convert Liter to Kg
To convert liter to kg we employ the formula m = D × V. For water at sea level at 39.2 Fahrenheit D = 1, so m = V. In this case one liter of water equals one kilogram.
For cooking water, the approximation kg ~ L most likely is good enough. But what about milk, sugar, flour etc? In this case, you substitute D in the ltr to kg formula with the particular density, or make use of our converters below. For the first converter, the value for D and the corresponding unit is needed, whereas the second converter works with average densities for frequent ingredients.
