Why does the conversion from liters to kg vary by substance?

The conversion depends on density (mass per unit volume). Different substances have different densities, so 1 liter of water (density ~1 kg/L) equals 1 kg, while 1 liter of oil (density ~0.92 kg/L) equals 0.92 kg.

Can I convert kilograms back to liters with this tool?

Yes, the tool includes a bidirectional conversion option. Simply select 'Convert kg to liters' and enter the kilogram value along with the substance density.

What is the formula for converting liters to kilograms?

The formula is: Kilograms = Liters × Density (kg/L). For example, 5 liters of water (density 1 kg/L) = 5 × 1 = 5 kg.

Which substances are included in the pre-defined list?

The tool includes water, milk, vegetable oil, gasoline, alcohol (ethanol), honey, and mercury. You can also use custom density for any other substance.
