0.5 Liters to Grams – How Many Grams Is 500 mL?

0.5 liters (500 mL) equals 500g of water, 515g of milk, or 710g of honey. The answer depends on the liquid, because liters measure volume and grams measure weight. Since 0.5 liters is the same as 500 milliliters, this page also covers the “500 mL to grams” conversion for the liquids listed below.

Why 0.5 Liters Isn't a Fixed Number of Grams

Liters measure volume, the space a liquid takes up. Grams measure weight. The link between the two is density: how much a given volume of a specific liquid actually weighs. Density behaves the same way when you need a different unit, so the same half liter can be written out in kilograms or in pounds without the volume changing at all.

The formula is:

grams = liters x 1,000 x density (g/mL)

Water's density is 1 g/mL, so 0.5 liters of water lands on a round 500 grams. Denser liquids like honey (1.42 g/mL) or maple syrup (1.32 g/mL) weigh more at the same volume, while lighter liquids like vegetable oil (0.92 g/mL) weigh less. The same formula scales to any volume, which is exactly what the full liters to grams converter does.

What 0.5 Liters Looks Like

0.5 liters is 500 mL, the size of a standard single-serve bottle of water. In US measures that works out to just over two cups, or a little more than a pint.

FAQ

How many grams are in 0.5 liters of water?

0.5 liters of water weighs about 500 grams. Water has a density very close to 1 gram per milliliter, so its volume in milliliters and its weight in grams are nearly the same number. Since 0.5 liters equals 500 milliliters, multiplying that by water's density of 1 gram per milliliter gives approximately 500 grams. This close match between milliliters and grams applies specifically to water and does not carry over to liquids with a different density.

How many grams are in 0.5 liters of milk?

0.5 liters of milk weighs approximately 515 grams. Milk is slightly denser than water, at about 1.03 grams per milliliter, mainly due to the fat, proteins, and natural sugars it contains. Since 0.5 liters is the same as 500 milliliters, multiplying that volume by milk's density gives 515 grams. The difference from water is small but consistent, so a measurement that assumes water's weight will come out slightly light if the liquid is actually milk.

Why does 0.5 liters of honey weigh more than 0.5 liters of water?

Honey is denser than water, meaning the same volume of honey packs more mass into the same space. Water has a density of about 1 gram per milliliter, while honey's density is closer to 1.42 grams per milliliter. At 0.5 liters, water weighs about 500 grams, while honey weighs about 710 grams. Both start from an identical volume, but honey's high sugar content and low water content make it noticeably heavier than the same amount of water.
