▾

Water 1.00 g/mL, Milk 1.035 g/mL, Oils 0.915–0.920 g/mL.

Use preset 0.916 g/mL to match 5 kg → ~5459 mL, or choose “Other” to input a custom value.

How the mL → kg conversion works

The calculator converts your input volume to cubic meters, multiplies by density (in kg/m³), then outputs the mass in your chosen unit. Presets for water, milk and cooking oil are included; choose “Other” to enter a custom density such as benzene or glycerin.

How to use the ml to kg calculator

  1. Select a substance (or “Other” for custom density).
  2. Enter the volume and unit (mL, L, cm³, m³).
  3. Pick your desired mass unit (mg, g, or kg).
  4. Adjust “Decimals” for display precision (default 0).

Common questions

  • How many mL is 1 kg? Depends on density: water → 1000 mL; oils commonly 0.915–0.920 g/mL (≈1087–1093 mL per kg); milk ~1.035 g/mL (≈966 mL).
  • What is 500 mL in kg? For water ≈ 0.5 kg; multiply volume (L) by density (kg/L).
  • Is 1 L equal to 1 kg? Only for water near room temperature.
  • How do you convert mL to kg? Mass (kg) = Volume (mL) × Density (g/mL) ÷ 1000.

An example using the ml → kg converter for benzene

Set Substance to Other, enter density 0.8765 g/mL (20 °C), type a volume like 250 mL, and choose kilograms. The result is m = 250 × 0.8765 ÷ 1000 ≈ 0.2191 kg.

Behind the scenes of the ml to kg calculator

The app avoids floating-point surprises by rounding only for display (you control decimal places). Internally it converts units first, then multiplies by density in SI (kg/m³), which keeps results consistent and scalable across units.

FAQs

How do I find the mass of 10 mL of water?
With water density ≈1 g/mL, multiply 10 mL × 1 g/mL = 10 g = 0.01 kg. Set volume to 10 mL, choose Water, and select kg.
How do I calculate the volume of 150 kg of chlorine gas at STP?
For gases you need density at the given conditions. Using ~3.2 kg/m³ at STP for Cl₂, volume ≈ 150 ÷ 3.2 ≈ 46.9 m³. This tool focuses on liquids/solids; gas results vary strongly with temperature and pressure.
