Grams to Liters : Convert g to L Instantly
To convert grams to liters, divide the weight in grams by the density of the liquid, then divide by 1,000. For water, 1,000 grams is 1 liter. For milk, oil, honey and other liquids the answer is different, so use the calculator above and pick your liquid.
Grams to Liters Formula
Grams measure mass and liters measure volume, so you need the density of the liquid to convert between them. With density in grams per milliliter (g/mL), the formula is:
Liters = grams / (1,000 x density)
The 1,000 turns milliliters into liters. If your density is in kg/L, it already equals the g/mL value, so the same formula works.
Grams to Liters Examples
- 500 g of water: 500 / (1,000 x 1) = 0.5 L
- 750 g of whole milk (1.03 g/mL): 750 / (1,000 x 1.03) = 0.7282 L
- 250 g of olive oil (0.91 g/mL): 250 / (1,000 x 0.91) = 0.2747 L
- 250 g of ethanol (0.789 g/mL): 250 / (1,000 x 0.789) = 0.3169 L
- 1,000 g of honey (1.42 g/mL): 1,000 / (1,000 x 1.42) = 0.7042 L
Grams to Liters Conversion Table
These values use the same densities as the calculator: water 1, milk 1.03, vegetable oil 0.92, olive oil 0.91 and honey 1.42 g/mL.

FAQ
How many liters is 1,000 grams?
For water, 1,000 grams is exactly 1 liter, because water has a density of 1 g/mL on this site. For other liquids the answer changes with density. 1,000 grams of milk is about 0.9709 liters, 1,000 grams of olive oil is about 1.0989 liters, and 1,000 grams of honey is about 0.7042 liters. Denser liquids take up less space per gram, so they give a smaller number of liters. Pick your liquid in the calculator and press Convert for the exact figure.
How do I convert grams to liters without knowing the density?
You need a density value, because grams measure mass and liters measure volume. If the liquid is water or close to it, use 1 g/mL and divide the grams by 1,000. For anything else, look for the density on the product label or a data sheet. Then choose Custom density in the calculator and enter it in g/mL, kg/L, g/L or another unit. If you only have a rough idea of the liquid, pick the closest match from the list.
Why does the same number of grams give a different number of liters?
Each liquid packs a different amount of mass into one liter. Oil is lighter than water, so 500 grams of it fills more than half a liter. Honey is heavier than water, so 500 grams of it fills less than half a liter. The grams stay the same, but the space they take up depends on density. That is why a single fixed grams-to-liters number only works for one liquid at a time.
How many milliliters is 1 gram of water?
One gram of water is 1 milliliter, which is the same as 0.001 liters. This is the easiest case because water has a density of 1 g/mL. It also means 1 gram of water equals 1 cubic centimeter. For other liquids, divide the grams by the density in g/mL to get milliliters, then divide by 1,000 for liters. You can also use the milliliters to grams calculator when you start from a volume instead of a weight.
Can I convert grams of flour or sugar to liters?
You can, but the result is only an estimate. Flour and sugar are powders, so their bulk density changes with how tightly they are packed and how much air they hold. Sifted flour takes up more room than scooped flour. If you know the bulk density of your product, enter it as a custom density. For baking, weighing on a kitchen scale is more accurate than converting dry ingredients to liters.
What is the difference between grams and liters?
Grams measure mass, which is how much matter something contains. Liters measure volume, which is how much space it takes up. Because they measure different things, there is no single conversion factor between them. You need the density of the substance to link the two. Water is the simple case at 1 g/mL, so 1,000 grams is 1 liter. Oils, syrups and alcohol all have different densities, so each one converts differently.
