Quick answers for 500 mL of water
For everyday fresh water estimates, 500 mL of water is about 500 grams. The exact number changes slightly with temperature and dissolved minerals, but the difference is small for normal bottle, kitchen, and carrying calculations.
This is the water-only weight, not the plastic bottle weight.
500 grams divided by 453.59 grams per pound is about 1.102 pounds.
This is different from 16.9 fluid ounces, which is a volume label on many bottles.
Add the plastic bottle, cap, and label. Many lightweight bottles add roughly 10–25 grams.
16.9 US fluid ounces is about 500 mL, so the water weighs about 1.10 pounds.
Real case weight is higher after bottle and packaging weight. Use the bottled water calculator for cases.

How to calculate 500 mL water weight
The simple everyday rule is that 1 mL of fresh water weighs about 1 gram. That means 500 mL weighs about 500 grams.
500 mL water ≈ 500 g
500 g ÷ 1000 = 0.5 kg
500 g ÷ 453.59237 ≈ 1.10 lb
500 g ÷ 28.3495 ≈ 17.64 oz
If you are weighing a physical bottled water product, add the bottle, cap, label, tray, shrink wrap, and case packaging. The water-only number is not always the same as the full retail package weight.

24-pack and 40-pack bottled water cases
The water in a 24-pack of 500 mL bottles weighs about 26.5 pounds. The water in a 40-pack weighs about 44.1 pounds. Real case weights are higher after packaging.
Kitchen, fitness, and travel estimates
For meal prep, backpack weight, gym bags, travel bags, and hydration planning, 500 mL is easy to remember: about half a kilogram or a little over one pound of water.
Fluid ounces vs weight ounces
Many bottles are labeled 16.9 fl oz. Fluid ounces describe liquid volume. Weight ounces describe mass. A 16.9 fl oz bottle holds about 500 mL of water, which weighs about 17.6 ounces by weight.
