There can be no equivalence.
A kilogram is a measure of mass. A millilitre is a measure of volume. The two measure different things and,according to basic principles of dimensional analysis, conversion from one to the other is not valid.
If you are not convinced, consider a millilitre of air. How many kilograms? Next consider a millilitre of water. How many kilograms?
The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
Furthermore, there is no simple link between volume and mass for water. A litre was defined so that the maximum density of pure water (at 4 deg C and 1 bar) was 1 gram per ml but that definition was replaced in 1964 - nearly 50 years ago.

What is 50 ml in kg?
This is not a valid conversion; kilograms (kg) and grams (g) are measures of weight or mass while milliliters (mL or ml) measure volume.
What is 3 liters - 720ml?
-717
If you have a volume of 10ml and a mass of 100 kg what is the density?
The density is 10 kg/mL
How muchis 7500 ml in kg?
To convert milliliters (mL) to kilograms (kg), you need to know the density of the substance in question. The density of a substance is its mass per unit volume. For water, which has a density of 1 g/mL, 7500 mL would be equal to 7500 grams. To convert grams to kilograms, you divide by 1000, so 7500 grams is equal to 7.5 kg.
A metal ball has a mass of 2kg and a volume of 6 ml What is its density?
density = mass / volume → density_ball = 2kg / 6ml = 1/3 kg/ml ≈ 0.333 kg/ml If you want it in other units: 1 ml = 1 cm³ → density ≈ 0.333 kg/cm³ 1 kg = 1000 g → density ≈ 333 g/cm³ 1 m³ = 1000000 cm³ → density ≈ 333,333 kg/m³ That is one dense material of which the ball has been made (mercury has a density of 13,594 kg/m³, so the material is about 25 times denser than mercury) - have you got your units correct?
