How much does a full gallon of whole milk weigh?

The weight of a gallon of milk is only about 3% greater than a gallon of water. At 8.6 pounds, a gallon of whole milk weighs slightly more than a gallon of 2% milk, which weighs 8.4 pounds. A gallon of water weighs in at 8.34 pounds and comes in right under the gallon of 2% milk. Milk is 87 % water, thus a gallon of milk will not differ much in weight from the water itself.

By weight:

Milk : 8.6 lb/gallon

Condensed milk : 9.4 lb/gallon

Cream: 8.28 lb/gallon

is this a US gallon or an Imperial gallon?

billyboy915

spg cool dude, PLEASE learn to use English properly. It is "should have" or "should've", but NEVER "should of"!

You should of mention if it is the US gallon or Imperial gallon in your question.

Gery Tillmanns

That would depend on the butter fat content and whether it's a US or Imperial gallon. Bad question.

Allan Player, what are you on about

Nodmirt

The question needs to specify US Gallons or Imperial Gallons as they are different.

I think you need to include the metric measure as well especially when you look at the huge number of nationalities that play Quizz Club.

Angel Palacios Zea

Very easy. Thanks.

John Conley

Too simple.

What the hell is a gallon?

Kaveri Bharath

Muddy Anthony Waters, the net doesn't have borders, so ask how many kgs a litre of full fat milk, at sea level, weighs. The rest of the world doesn't measure in gallons, pints, and pounds!

Kaveri Bharath

Neatly divide, I meant

Kaveri Bharath

Complete fluke, that I got it right! No clue how much a gallon is, and how much a pound is.... METRIC PLEASE, 'MERICA!! Even the stick-in-the-mud Brits have moved to metric. In general it's easier when things nearly divide into 10s and 100s, rather than 12s and 16s. Life with percentages and decimals is so so easy!

With fat in the milk, the density should be less than water.

Ian Swindale, the cream is lighter than milk, it floats on top of milk therefore it’s less dense than milk.

I wish that in all instances a question such as this would use metric units. The metric unit world wide is standardised. Whereas within the imperial system there are variances between the European units and the US units. E.g. a US Gallon is roughly 3.8 litres, a European Gallon is 4.5 litres. This would save a bunch of guessing any hypothesising over the origin of the question. Just saying!

US or imperial gallon ? Depends on the region you live in !

Mark Sutter

Wow, I can't believe I guessed right on that one !

Colin Semmler

USA still uses imperial measurements so the majority of the world would not have a clue about this old-fashioned stuff. And milk varies in weight (or mass).... even to the type of animal from which it comes.
