does 1 liter = 1 kg?

If the liquid is H2O, yes. To convert volume to mass, you need to know the density. They are not the same thing.
Volume = Mass/Density

and the volume you're talking about is in liters?

1 mL = 1cm (for water)

so

convert it to figure it out :)

?

To convert volume to mass, you need to know the density of the substance. In the case of water (H2O), the density is 1 gram per milliliter (g/mL) or 1 kilogram per liter (kg/L). So, if you have 1 liter of water, the mass would be 1 kilogram.

To convert volume in milliliters (mL) to liters (L), you can use the conversion factor: 1 mL = 0.001 L.

So, if you have 1 milliliter of water, the volume would be 0.001 liters, and the mass would be 0.001 kilograms (1 gram).

Therefore, for water, 1 liter is equal to 1 kilogram, and 1 milliliter is equal to 1 gram. However, this is specific to water, and for other substances, the density and conversion factors may be different.
