Unit Converters

Kg to mL (Mass to Volume by Substance)

Convert kilograms to milliliters for ten common substances. Water is 1,000 mL per kg, but denser liquids like honey take less volume and lighter ones take more.

How to use
  1. Enter a mass in kilograms.
  2. Choose the substance from the list.
  3. Switch the substance to compare densities.

How it's calculated

mL = kg × 1000 ÷ ρ

kg = mass in kilograms, mL = volume in millilitres, ρ = density in g/mL (water ≈ 1). Reverse: kg = mL × ρ ÷ 1000.

Common questions

Why does 1 kg of honey take less volume than water?

Honey is denser, so a kilogram of it packs into about 704 mL rather than the 1,000 mL a kilogram of water fills.

At what temperature are these densities measured?

The densities are reported at 20 °C, a standard reference point from NIST and USDA data.
