Our kg to mL converter can help you convert between the mass of any substance in kg to its volume in mL.

Continue reading to know the relation between mass and volume. You will also find answers to questions like:

  • How to convert kg to mL?
  • How many mL in a kg of water or milk?

First, let us start with the basics of kg to mL conversion.

Kg to mL conversion formula

As you already know that kg or kilogram is a unit of mass, i.e., the quantity of matter in any object. Whereas, mL or milliliter is a unit of volume, i.e., the space occupied by matter.

To convert between mass and volume, we can use a very simple formula:

Volume=MassDensity\rm Volume = \frac{Mass} {Density}

In the above equation, the mass, density, and volume of the substance are expressed in the S.I units, i.e., kg, kg/m3, and m3, respectively.

Now, using the fact that 1 m3 = 106 mL, we can write the formula for kg to mL conversion as:

Volume(mL)=Mass(kg)Density(kg/m3)×106 mL/m3\rm Volume (mL) = \frac{Mass (kg)}{Density (kg/m^3)} \times 10^6~ \rm{mL/m^3}

Kg to mL conversion example

Let us consider a simple example of converting 1 kg of milk to ml. We know that the density of milk is about 1030 kg/m3.

Hence, we can calculate its volume in mL as:

Volume(mL)=1 kg1030 kg/m3×106 mL/m3=970.9 mL\begin{align*} \text{Volume} (\rm{mL}) &= \frac{1~\rm{kg}} {1030~ \rm{kg/m^3}} \times 10^6~ \rm{mL/m^3} \\ & = 970.9~ \rm{mL} \end {align*}

i.e., 1 kg of milk is equivalent to about 970.9 mL.

As you can see converting from kg to mL is very easy if you know the density of the substance of interest.

How to use the kg to mL converter?

Now let us see how we can use the kg to mL converter for the same problem:

  1. Using the drop-down menu, select the category as "food" and "milk".

  2. The density field will auto-populate. You can also enter the density if you know its value.

  3. Input the weight/mass as 1 kg. The tool will display the volume of milk as 970.9 mL.

How do I convert kg to mL?

To convert kg to mL for any substance, follow the given instructions:

  1. Find out the density of the substance in kg/m3.

  2. Now divide its mass in kg by its density in kg/m3 to get its volume in m3.

  3. Multiply the volume in m3 by 106 to get the volume in mL.

How many mL in a kg of water?

About 1,000 mL. The density of water is about 1000 kg/m3. Hence, the volume of 1 kg of water is about 10-3 m3 or 10-3 × 106 = 1,000 mL.
