Density sources
Presets are typical published values; natural products vary. For exact laboratory work, use Custom.
- Water (1.00 g/mL): Definitional: 1 mL of water at 4 °C has a mass of 1 g.

- Table salt (fine) (1.22 g/mL): Fine table salt, typical bulk density.
- Butter (0.96 g/mL): King Arthur Baking: 227 g per US cup = 0.9595 g/mL, rounded.
Frequently asked questions
What is the formula to convert kg to mL?
Volume in milliliters = (mass in kilograms x 1000) / density in g/mL. The 1000 converts kilograms to grams, and dividing by density (grams per milliliter) gives milliliters. Example: 2 kg of milk at 1.03 g/mL is 2 x 1000 / 1.03 = 1941.75 mL.
How many mL is 1 kg?
It depends on the density of the substance. 1 kg of water is exactly 1000 mL. 1 kg of milk is 970.87 mL, 1 kg of honey is 704.23 mL, and 1 kg of flour is 1960.78 mL. Only water, with density 1.00 g/mL, gives the neat 1000 mL answer.
How many mL is 1 kg of water?
Exactly 1000 mL, which is 1 liter. Water has a density of 1.00 g/mL by definition near 4 C, so 1 kg x 1000 / 1.00 = 1000 mL. By the same math, 2.5 kg of water is 2500 mL.
How many mL is 1 kg of milk?
About 970.87 mL for whole milk (density 1.03 g/mL): 1 x 1000 / 1.03 = 970.87 mL. Low-fat milk is very slightly less dense, so the difference is under 1 mL per kilogram.
How many mL is 1 kg of honey?
About 704.23 mL: 1 x 1000 / 1.42 = 704.23 mL. Honey is much denser than water, so 5 kg of honey is only 3521.13 mL. In reverse, 500 mL of honey weighs 0.71 kg.
How do I convert kg to mL for flour or sugar?
Use the bulk density of the ingredient. 1 kg of all-purpose flour (0.51 g/mL) is 1960.78 mL, about 8.29 US cups. 1 kg of granulated sugar (0.85 g/mL) is 1176.47 mL. Packing (spooned vs scooped) can shift flour density by about 10 percent, so treat these as practical approximations.
How do I convert mL to kg?
Reverse the formula: mass in kilograms = (volume in mL x density in g/mL) / 1000. Example: 2000 mL of milk at 1.03 g/mL is 2000 x 1.03 / 1000 = 2.06 kg. Use the direction switch in the converter above to convert milliliters to kilograms.
Can I use a custom density?
Yes. Choose Custom and enter the density in g/mL, kg/L, or lb/gal. Note that 1 g/mL = 1 kg/L exactly, and 1 lb/gal = 0.119826 g/mL. Example: 2 kg at 0.80 g/mL is 2500.00 mL, and 2500 mL at 1.26 g/mL is 3.15 kg.
Is 1 kg always equal to 1 liter?
No. That is only true for water and liquids with density 1.00 g/mL. 1 kg of vegetable oil (0.92 g/mL) is 1086.96 mL, while 1 kg of salt (1.22 g/mL) is only 819.67 mL. Kilograms measure mass; liters measure volume.
Does temperature change the kg to mL result?
Slightly. Most liquids expand when warm, so their density drops a little. Water at 20 C is about 0.998 g/mL instead of 1.000, changing 1 kg by roughly 2 mL. For cooking and everyday conversions the difference is negligible; for lab work, use the density at your working temperature.
How accurate are the preset densities?
Each preset is a published typical value with its source listed under the converter: water 1.00 g/mL (definitional), milk 1.03, vegetable oil 0.92 (USDA), honey 1.42 (USDA), granulated sugar 0.85, all-purpose flour 0.51 (King Arthur 120 g/cup), table salt 1.22, butter 0.96 (King Arthur 227 g/cup). Natural products vary, so use Custom for exact laboratory values.
What is the difference between this converter and the grams to mL converter?
This page converts kilograms to milliliters, the scale used for bulk ingredients and shopping quantities. For gram-scale amounts, see our grams to milliliters converter, which uses the same density table: 100 g of milk is 97.09 mL there, versus 1 kg = 970.87 mL here.
How many US cups is 500 g of flour?
500 g (0.5 kg) of all-purpose flour is 980.39 mL at 0.51 g/mL, which is 4.14 US cups (1 US cup = 236.588 mL). The converter above also shows liters and US cups automatically with every conversion.
Why cannot I convert kg to mL without knowing the density?
Because kilograms measure mass and milliliters measure volume, there is no universal conversion factor. The link between them is density, mass per unit volume. A kilogram of feathers and a kilogram of lead occupy very different volumes, which is why this converter always asks for a substance or a density first.
