No, 1 kg and 1 liter are not the same. Kilogram (kg) is a unit of mass, measuring the amount of matter in an object, while liter is a unit of volume, measuring the amount of space occupied by a substance. The relationship between mass and volume depends on the density of the substance. In the case of water, 1 liter of water has a mass of approximately 1 kg, but this is not a universal equivalence for all substances.

Not in all cases. The litre is equal 1/1000 m3. This volume of water = 1 kilogram of water at 4oC (the maximum density of water). A litre of other liquids will not necessarily have a mass of one kilogram, as examples a litre of pure alcohol will have a mass of about 0,8 kg and liter of Mercury (Hg) will have amass of 13,6 kg.
Yes.
One liter is composed of 1,000 cubic centimeters (cc) . One cc, which is also the same as a milliliter (mL) of water, weighs one gram. Therefore, a liter of water (1000 mL) weighs 1 kilogram (1000 g).
At different temperatures, the density of water is slightly different. At any other temperature than 4 °C, the density of water is in fact lower. However, the change is very small, and so to a very close approximation, the weight of 1 liter of water is 1 kg at most temperatures.
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).
Liters and kilograms of what substance? Liters are a measure of volume, kilograms are a measure of mass. You will need the substance's density to find its mass in kilograms.
They are not the same. A kilogram is a measure of weight. A liter is a measure of volume. One liter of lead weighs a lot more than on kilogram.
