Milliliters to Kilograms Calculator

Convert volume to mass using water density (1 g/ml)

Milliliters (ml)

Kilograms (kg)

ℹ️

Important Note

This calculator assumes water density (1 g/ml). Different substances have different densities, so results will vary for other liquids. For example, oil is lighter (~0.9 g/ml) while honey is heavier (~1.4 g/ml).

📚 Examples, Formula, and How To

📝 Milliliters to Kilograms Formula

Milliliters to Kilograms (Water)

kg = ml ÷ 1,000

For water: divide milliliters by 1,000 to get kilograms (density = 1 g/ml)

Kilograms to Milliliters (Water)

ml = kg × 1,000

For water: multiply kilograms by 1,000 to get milliliters (density = 1 g/ml)

💡 Converting Milliliters to Kilograms

Example 1

Convert: 500 milliliters of water to kilograms

Start with the conversion formula: kg = ml ÷ 1,000

Substitute the value: kg = 500 ÷ 1,000

Calculate: 500 ÷ 1,000 = 0.5

Result:0.5 kg

Example 2

Convert: 2 kilograms of water to milliliters

Start with the conversion formula: ml = kg × 1,000

Substitute the value: ml = 2 × 1,000

Calculate: 2 × 1,000 = 2,000

Result:2,000 ml

📚 What are Milliliters and Kilograms?

📏 Milliliter(ml)

Definition:

A milliliter is a unit of volume equal to one thousandth of a liter. It is commonly used for measuring liquid volumes.

History:

The milliliter was established as part of the metric system, derived from the liter which was originally defined as the volume of one kilogram of water.

Common Uses:

Cooking and recipe measurements
Medical dosages and prescriptions
Laboratory measurements
Beverage serving sizes
Cosmetic and personal care products

💡

Fun Fact:

One milliliter is exactly equal to one cubic centimeter (1 ml = 1 cm³). A teaspoon holds about 5 ml, and a tablespoon holds about 15 ml!

📏 Kilogram(kg)

Definition:

A kilogram is the base unit of mass in the International System of Units (SI). Originally defined as the mass of one liter of water at 4°C.

History:

The kilogram was originally defined in 1795 as the mass of one liter of water. In 2019, it was redefined based on fundamental physical constants.

Common Uses:

Body weight measurements
Food and ingredient quantities
Scientific research and calculations
Industrial measurements
International trade and commerce

💡

Fun Fact:

The kilogram is the only SI base unit that still has a prefix ('kilo-'). One kilogram of water at room temperature occupies almost exactly one liter of space!
