Does a pint of milk weigh the same as a pint of water?!


Question:

Does a pint of milk weigh the same as a pint of water?

I know a pint of water weighs 568g but would a pint of milk weigh the same?


Answers:
The density of cows milk depends on how it has been pasteurised but a skimmed milk is 1033kg/m3.

Water is exactly 1000kg/m3 so the mi8lk would be heavier. It would weigh 586.7g

I'd imagine so. Its all liquid sure

yes, all liquid type pints weigh about a pound, milk, water, juices, cream ect
things that don't are things like heavy syrups

my guess is that milk is heavier as it mainly made of lactose (fat)

one way to find out without scales would be to mix them and wait a few days to see if it separates.

It should be very close since Milk is essentially water with some fat and milk sugars which would make Milk slightly heavier.

For whole milk (based upon the website below), the weight of a pint of whole milk is 584.5 g

no it depends on the milk whether or not its full cream ,semi skimmed or skimmed milk hope this helps

i would think that milk would be slightly heavier then water...so is it the same or is milk heavier?

Not all liquids are created equally.

Water is easy to weigh, 250mL=250g. but with milk it's slightly heavier. I don't have my theory book from pasty school with me, but if you have a scale, measure 250mL of milk, then weigh it and see what you get. Then you can just do the math.

Hope that helps

A pint is a pint-they both weigh the same I would think.

You're trying to equate volume and weight. They aren't the same thing. A pint of water would probably weigh less than a pint of milk.

yes, just as a pound of lead weighs the same as a pound of cotton balls....weird isn't it?

probly not maybe a little bit more

The milk is probably barely heavier than water because it contains fat. But if you were to hold them both in each hand, i doubt you could tell the difference.

no. milk is more dense.

I would guess no since they have different densities.

Okay this was my worst subject in HS, but
I think this is right.

A U.S. pint is equal to 473 ml. depending on
who you ask. This is a measure of volume.
And weight is sometimes specific gravity
and sometimes not.

Pure water at 4°C (max. density) was chosen as the 'base line' for specific gravity and given the value of 1.

Milk, at 15 degrees Centigrade, is between
1020-1050 kg/cu.m (kilograms/cubic meter) at 4 degrees C. is 1000 kg/cu.m.

So the specific gravity of milk given
by the source is higher than it is for
pure water, but the temperatures given were
different. You'd have to discover what the
change is in specific gravity by increasing
one or the other substances by temperature
until they are both the same.

yes ...its like a pound of cotton wool weighs the same as a pound of iron..;) only the cotton wool would look like a heap compared to the iron.
