kg to mL Calculator
Convert kilograms to milliliters using substance density. Since kilograms measure mass and milliliters measure volume, you need the density of the substance to convert between them. Useful for cooking recipes and lab measurements.
How to Convert kg to mL
- Identify the substance and find its density in kg/L.
- Divide the mass in kilograms by the density to get liters.
- Multiply the liters by 1000 to get milliliters.
Formula
mL = (Kilograms ÷ Density) × 1000
Example Calculation
Convert 0.5 kg of honey to mL:
Density of honey = 1.42 kg/L
Volume = (0.5 kg ÷ 1.42 kg/L) × 1000 = 352.11 mL
Substance Density Reference Table
| Substance | Density (kg/L) | 1 kg = mL |
|---|---|---|
| Water | 1 | 1000.00 mL |
| Milk (whole) | 1.03 | 970.87 mL |
| Cooking Oil | 0.92 | 1086.96 mL |
| Honey | 1.42 | 704.23 mL |
| Gasoline | 0.75 | 1333.33 mL |
Frequently Asked Questions
How many mL is 1 kg of water?
Since water has a density of 1.0 kg/L, 1 kg of water equals exactly 1000 mL (1 liter).
Is 1 kg always 1000 mL?
No, only for water. For other substances, the volume depends on density. For example, 1 kg of honey is only about 704 mL because honey is denser than water.
How do I convert kg to mL for cooking oil?
Cooking oil has a density of about 0.92 kg/L. So 1 kg of oil = (1 ÷ 0.92) × 1000 = approximately 1087 mL.
Why is density needed for this conversion?
Kilograms measure mass and milliliters measure volume. Without knowing the density, there is no way to determine how much space a given mass occupies.
What if I don't know the density of my substance?
Check the product label, a material safety data sheet (MSDS), or a chemistry reference. You can also use the Custom option in the calculator above to enter any density value.
