What is the weight of one gallon of transformer mineral oil?

Answer 1

About 6 lbs per gallon.

Answer 2

As a rough guide engine oil usually weighs about 0.87 kg/litre or about 7.2 pounds per US gallon. Unfortunately a rough answer is the best that can be done as there are hundreds of different types of engine oil with slightly different densities. To get an exact density we would have to know the details of the oil you're using. For a really accurate answer we would also have to state the temperature as the density of oil as with most fluids varies with temperature. Most oil manufacturers' provide data sheets for their products that should include density. If you search the manufacturers web site you should be able to get an accurate figure for a particular grade.

Answer 3

64oz a gallon, which would be 4 pounds.

---------------------------------------------------------------------------

I believe the answer given above is erroneous.

A gallon contains 64 ounces in volume, not weight. A gallon of paint and a gallon of water will occupy the same volume of space but have different weights. Water is approximately 8.34 pounds. I believe mineral oil far more dense would weigh more than water.

In weight measurements, 64 oz = 4 pounds

---------------------------------------------------------------------------

A gallon is 128 fluid ounces, not 64. And of course, fluid ounces are not a measurement of weight, only volume.

Mineral oil is generally classified by its weight, being referred to as 'light,' 'heavy,' 'extra heavy,' etc. This classification describes the density of that particular oil, so the heavier the oil, the more a gallon of it would weigh.

Generally, though, a gallon of mineral oil will weigh from 9 to 11 pounds (typically on the lighter side of that range, though).

-----------------------------------------------------------------------------------------------

I have deleted the misinformed reply regarding "oil being lighter than water". Oil is not lighter than water (not even machine oil) it is more dense, causing it to have greater buoyancy. This is why it floats atop water! If what was written here was true, then the same could be said for an aircraft carrier made out of steel... and the only similarity between the aircraft carrier & oil being lighter than water, is that neither is true.

Mineral oil has a density of roughly 0.8 g/cc. There are about 3400 cc/gal. That yields a mass of a little over 3000 grams to the gallon. Once converted to ounces and pounds, the weight is around 6.68 lb/gal.

Oil (or an aircraft carrier, for that matter) doesn't float on water because it is denser. There is a confusion between density and weight here. Rocks are much denser than water. They sink, with the exception of pumice and other volcanic rocks with many air pockets. The presence of the air pockets in the structure of those rocks is what causes them to float. The air lowers the over-all density of the rock. The same is true of an aircraft carrier. Were you to fill the same volume with solid steel, that carrier would sink. Because there is so much open space within any such vessel, the vessel's over-all density is much lower than that of water. An equal volume of water would actually weigh much more than any ship. That is why they float.

Please don't conflate weight with density. They are related, but oil is "lighter than water" in the sense that it is less dense. I.e. it has a lower specific gravity than water. Mineral oil's specific gravity is .92. Of course, water is the standard that all specific gravity is compared to, so it has an specific gravity of 1.

Answer 4

The weight of one gallon of transformer mineral oil is around 7.5 to 8.5 pounds, depending on the specific type and brand of oil.

Answer 5

1 gallon soy oil weighs between 7.35 lbs to 7.5 lbs

Industry standard is 7.35lbs

Answer 6

Depending on the use of the mineral oil, it can have different densities. Typically it weighs about 0.8 grams per cubic centimeter.

Answer 7

Just under 7 pounds (6 pounds, 14.8 ounces)

Answer 8

The specific gravity of 70 nf mineral oil ranges from 0.833 to 0.861. This gives a gallon the mass of 3.16 to 3.26 kilograms, or 6.97 to 7.19 pounds.

Answer 9

7.6 pounds/gallon

Answer 10

About 7 pounds
