Gram to Liter Conversion Calculator
Convert a mass in grams into a volume in liters. Because density varies by substance — 1 gram of honey takes far less space than 1 gram of ethanol — you need to select or enter the substance density.
g
Substance
Volume in liters at the given density
- 1
Volume in mL
500 ÷ 1 = 500mL = mass ÷ density (g/mL) - 2
Convert to liters
500 ÷ 1000 = 0.5000
How does this calculator work?
To convert grams to liters, divide by the density in g/L (= density in g/mL × 1000). For water (1 g/mL): 500 g ÷ 1000 = 0.5 L. For honey (1.42 g/mL): 500 g ÷ 1420 ≈ 0.352 L. Select or enter the substance density to get the right answer.
Formula
How this is calculated
Mass and volume are not the same thing. Volume depends on how densely packed the molecules are, which differs for every substance. The relationship is: Density = Mass ÷ Volume, rearranged to Volume = Mass ÷ Density.
Density is most commonly expressed in g/mL (grams per milliliter), where 1 mL is the same as 1 cm³. To get liters, divide by 1000: 1 L = 1000 mL. So Volume in liters = Mass in grams ÷ (Density in g/mL × 1000). For water the density is almost exactly 1 g/mL at room temperature, so 500 g of water is about 0.5 L. A denser liquid like honey (≈ 1.42 g/mL) gives a smaller volume for the same mass, while a lighter liquid like vegetable oil (≈ 0.92 g/mL) gives a larger volume.
Density values used here are standard reference figures at approximately 20 °C and normal atmospheric pressure. Real-world values vary slightly with temperature, brand and composition. If you need higher precision, measure the density of your specific batch and enter it as a custom value.
Frequently asked questions
Exactly 1 liter. Water has a density of 1 g/mL (1000 g/L), so 1000 g ÷ 1000 g/L = 1 L.
Yes — as long as you know the density. Select a substance from the list or enter your own density in g/mL. The formula is the same: liters = grams ÷ (density × 1000).
Yes. One milliliter equals one cubic centimeter, so g/mL and g/cm³ are identical units numerically.
