One of those many questions that people have, whether they need to know or out of sheer curiosity, is whether all liquids weigh the same
And if not, which liquids weigh the most and which are the lightest?
Contrary to what you might think, not all liquids weigh the same in terms of pounds and ounces
Like solids, liquids have different densities and components that determine how heavy they are
However, while they may be similar, most liquids of the same volume do not weigh the same amount
Various liquids such as water, oil, milk, liquor, and so many more have different densities
How Much Does Water Weigh? Here is a table showing how much different quantities of water weigh
Because water is the most common of all liquids, it is often what other liquids are compared to in terms of weight and density

In terms of density, which is what determines how heavy a liquid is, mercury is the heaviest liquid in the world
Mercury is 136 times denser than water, which means it weighs quite a bit more per gallon
However, mercury in its liquid form is extremely deadly, so you should definitely not try to weigh the two liquids yourself
Steel, iron and lead are heavier than water when melted into a liquid
For example, water is more than ten times denser than hydrogen in its liquid form and is, therefore, more than ten times heavier
Liquid propane, which is what millions of people around the world rely on for their energy, weighs about half that of water
However, in terms of liquids we use or see every day, alcohol and oil are two of the lightest in the world
Alcohols such as ethanol, methanol, and isopropyl weigh about 79 grams per cubic meter, while water weighs 1 gram per cubic meter
If you have ever mixed oil and water, you have probably noticed that the oil floats on top of the water and does not mix with it
This is because oil is slightly lighter than water
As we just learned, alcohol is slightly lighter than water, which seems to indicate that wine weighs less than water
However, on average, wine is only about 10% alcohol, and the rest is made up of sugar and other additives
Basically, it all depends on what type of wine you are pairing with water
Wine that is high in alcohol content and low in sugar will weigh less than water
However, certain commercial wines with high sugar content and low to medium alcohol content will only weigh the same amount as water or more
Does Alcohol Sink Or Float? If you ever try to mix pure alcohol such as ethanol, methanol, or isopropyl with water, you will have a hard time
Pure alcohol is lighter than water, which means it will float on top rather than mixing or sinking to the bottom
Is Water Heavier Than Coffee? Whether or not water is heavier than coffee depends on the type and texture of the coffee
Whole coffee is expected to sink in water which means it is denser
However, liquid coffee is different in weight and density from whole coffee

Do Milk And Water Weigh The Same? Milk and water are two of the most similar liquids there are in terms of weight and texture
However, milk actually weighs slightly more than water when you compare a gallon of milk to a gallon of water
Milk is only 87% water and the rest is made up of components that are heavier than water, apart from fat
Fat is lighter than water, so, in theory, if milk has a high enough fat content, it can be as light as water
However, there is rarely if ever enough fat in milk to make it equal in weight to water
In terms of household liquids and what they weigh, the pyramid looks like this from heaviest to lightest: syrup, milk, water, oil, and alcohol
