188 ml is approximately 0.188 kilograms, assuming the substance has the same density as water.
Since 1 milliliter (ml) of water has a mass of about 1 gram (g), converting 188 ml to kilograms (kg) involves converting grams to kilograms by dividing by 1000. This direct relation applies mainly to water or liquids with similar densities.

Conversion Formula
The formula to convert milliliters (ml) to kilograms (kg) depends on the density of the liquid. For water, 1 ml equals 1 gram (g). Since 1 kilogram equals 1000 grams, the conversion formula is:
kg = ml × density (g/ml) ÷ 1000
For water, density is 1 g/ml, so:
kg = ml × 1 ÷ 1000 = ml × 0.001
This works because mass equals volume times density. Volume in ml multiplied by density in g/ml gives mass in grams, then dividing by 1000 converts grams to kilograms.
Example: Convert 188 ml of water to kg:
- Mass in grams = 188 ml × 1 g/ml = 188 g
- Mass in kilograms = 188 g ÷ 1000 = 0.188 kg
Conversion Example
- Convert 250 ml to kg:
- Multiply 250 ml by 1 g/ml = 250 g
- Convert grams to kilograms by dividing by 1000: 250 ÷ 1000 = 0.25 kg
- Convert 75 ml to kg:
- Mass in grams: 75 × 1 = 75 g
- Mass in kilograms: 75 ÷ 1000 = 0.075 kg
- Convert 500 ml to kg:
- 500 × 1 = 500 g
- 500 ÷ 1000 = 0.5 kg
- Convert 1000 ml to kg:
- 1000 × 1 = 1000 g
- 1000 ÷ 1000 = 1 kg

Conversion Definitions
Milliliter (ml): A milliliter is a metric unit of volume, equal to one-thousandth of a liter. It is used to measure small quantities of liquids and gases. One milliliter corresponds roughly to the volume occupied by one cubic centimeter (cc) of water at standard temperature and pressure.
Kilogram (kg): The kilogram is the base unit of mass in the International System of Units (SI). It equals 1000 grams and is used worldwide to measure the mass of objects. Kilograms quantify how heavy an object is by the amount of matter it contains, regardless of gravity.
Conversion FAQs
Can I convert ml to kg directly for all liquids?
Not always. The conversion depends on the liquid’s density. Water has a density of 1 g/ml, so 1 ml equals 1 gram. For substances with different densities, you must multiply by that density to get the correct mass in grams before converting to kilograms.
What if the liquid is denser than water?
If a liquid is denser than water, it means 1 ml weighs more than 1 gram. You multiply the volume by the density to find mass, then convert to kilograms. For example, mercury has a density around 13.6 g/ml, so 1 ml equals 13.6 g or 0.0136 kg.
Is the ml to kg conversion affected by temperature?
Temperature affects density slightly, so volume-to-mass conversions can change with temperature. Warmer liquids tend to expand and become less dense, so the mass per ml decreases. For most everyday purposes, these changes are minimal and can be ignored.
Why is the conversion factor 0.001 for water?
Because 1 ml of water has a mass of 1 gram and 1 kilogram equals 1000 grams, dividing the number of milliliters by 1000 converts grams to kilograms. So multiplying ml by 0.001 directly converts volume in ml to mass in kg for water.
Can I use this conversion for solids?
No, milliliters measure volume, which is not a direct measure of mass for solids unless you know the density. Solids often have irregular shapes and air gaps, so volume-to-mass conversions require precise density values or weight measurements.
