One liter is how many kilogram?

Answer 1

You need to know one liter of what. One liter of water weighs 1 kg at 4 degrees Celsius and one standard atmospheric pressure. For other liquids, multiply 1 kg by its specific density to get to its mass (at the same temperature and pressure).

Answer 2

"Liter" is a measure of volume, space, or capacity. "Kilogram" is a unit of mass.

They have different physical dimensions, measure different types of quantities,

and can't be converted to each other.

In order to relate a volume and a mass, you'd have to know what specific substance

is involved, as well its temperature and the pressure on it.

For example:

One liter of water at standard temperature and pressure has one kilogram

of mass. But one liter of water under other conditions, or one liter of any other

substance, doesn't.

Answer 3

The conversion between liters and kilograms will depend on the substance's density. One liter of water weighs approximately 1 kilogram. However, for other substances, the weight of one liter can be different.
