In the US system, 1 gallon of water weighs 8 lbs. So a US gallon of oil will weigh around 6.4 lbs.
Weight of a 55-gallon drum of oil: 444 lbs (201 kg)
Common ISO grades for use with hydraulic systems include 32, 46 and 68. Sometimes, 10, or 10 weight is mentioned as well.
|1 Gallon = 7.61 Pounds||3 Liters = 6 Pounds|
|1 Gallon = 3.45 Kilograms||3 Liters = 2.74 Kilograms|
|35 Lbs = 17.41 Liters||5 Gallons = 38 Pounds|
|35 Lbs = 4.59 Gallons||5 Gallons = 18.9 Liters|
|35 Lbs = 588.7 Ounces||5 Gallons = 17.26 Kilograms|
32 is thinner, No. 46 is medium and No. 68 is thicker. Generally speaking, if the temperature is low in winter, use #32 & #46 hydraulic oil with a lower viscosity, and use #68 hydraulic oil with a higher viscosity in summer.
|Gallons of water||Pounds||Kilos|
|3 gallons||24.99 lb||11.33 kg|
|4 gallons||33.32 lb||15.11 kg|
|5 gallons||41.64 lb||18.89 kg|
|6 gallons||49.97 lb||22.67 kg|
One US gallon of water weighs 8.34 pounds at 62°F, consequently, to find the total weight, we only need to multiply the 55 gallons by the gallon weight. This simple calculation shows us that 55 gallons of water weighs 458.7 pounds, or 208.06 kilograms.
Water is more dense (heavier) than oil so they can’t mix. Oil floats above the water.
If you use oil that is too thick, then the pump may not be able to draw it efficiently from the reservoir and cavitation may occur. If the oil is too thin then internal slippage may occur within the system’s components making it operate less efficiently.
AW 32 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 32. This is the thickness of the fluid tested at 40 degrees Celcius. ISO VG 32 has good cold weather flow capabilities and its thickness is equivalent to a SAE 10 weight lubricant.
ISO 32 is simply a viscosity range for industrial oils, normally used in hydraulics, it says nothing about any additives that may be present. AW 32 is required to contain anti wear agents, it may also contain other additives, but may be harmful in certain applications.
For example, AW 46 hydraulic oil is used to operate the hydraulic systems in off road equipment such as dump trucks, excavators, and backhoes, while AW 32 hydraulic oil colder weather application, like in a snow plow’s pump.
Water has a density of 1 kg /L, that is, 1 liter of water has a mass of exactly 1 kg. … This is because the oil has a lower density than water: about 0.91 kg / L. That is, 1 liter of water and 1 liter of oil have the same volume, but 1 liter of water is heavier than 1 liter of oil.
Calculate the weight of the oil in the container by subtracting the weight of the empty container from the weight of the container containing the liquid: X (weight of oil) = A (weight of container with oil) – B (weight of empty container). Convert these values to more convenient units if desired.

“Is it all right to mix an R&O hydraulic oil with an AW hydraulic oil in a hydraulic application?” Mixing oils with different additive packages is never recommended. Doing so could compromise the additive performance of both constituents, cause corrosion of component surfaces and lead to increased mechanical wear.
In practical terms, density is the weight of a substance for a specific volume. The density of water is roughly 1 gram per milliliter but, this changes with temperature or if there are substances dissolved in it. Ice is less dense than liquid water which is why your ice cubes float in your glass.
One gallon of jet fuel weighs approximately 6.7 pounds. The fuel can expand and contract with temperature changes, so the weight of one gallon can vary a bit. 6.7 pounds per gallon is the average for “normal” conditions. , 25+ years of aviation in a wide range of types.
A gallon of sand weighs approximately 12.5 pounds (5.6 kg). This weight depends on how wet the sand is, the materials in the sand, and the size of the sand particles.
The density of water(1000 kg/m3) is higher than the density of oil(870 kg/m3). According to the mathematical equation, mass =density*volume. Now keeping the same volume for both water and oil the mass would be greater for water. Hence the water is heavier than oil.

SAE 10W is equivalent to ISO 32, SAE 20 is equivalent to ISO 46 and 68, and SAE 30 is equivalent to ISO 100. As you can see, there is a bit of a difference between ISO 68 and SAE 30. The viscosity of the fluid largely determines the oil temperatures within which the hydraulic system can safely operate.
