90 Weight Gear Oil

The weight of the machine oil (engine or gear oil) depends on the chemical composition of the group. Its weight is determined by the density of the substance per unit volume (kg/m3). The density of the oil is determined using a pycnometer at +20 °C, since it depends directly on the temperature – the higher it is, the lower is the density of the oil product To conversion of liters (l) of engine oil into kilograms (kg) or vice versa, the density must be taken from the density table (average value) or from the lubricant manufacturer’s data (exact data). If the oil temperature deviates from the specified value, a correction factor must be used.

How much does 1 liter of engine oil weigh?

The ratio of mass to volume of an oil is determined by its density. However, this value, like viscosity, is highly dependent on temperature. Therefore, to calculate the exact liters of engine oil in kilograms, they should be measured at room temperature. However, it should also be taken into account that the density varies depending on the quantity and quality of additives, and if it is necessary to convert liters/ton of used oil into kg, the density parameters also change due to the admixture of wear products and carbon deposits (increased by 4-6%). To determine how much 1 liter of oil weighs, the density formula is used: ρ = m / V, where p is density (kg/m³), m is mass (kilogram) and V is volume (m³). The average value for 1 liter of engine oil is 0.850… 0.910 g, depending on the density of the oil.

Density table for engine oils

The density of an engine oil varies between 0.84 and 0.91 kg/l, depending on the SAE classification and kinematic viscosity (cSt). It is quite unstable and decreases with increasing temperature.

The density of a semi-synthetic engine oil is 3 – 7% higher than that of a pure synthetic. The higher the temperature of the oil, the lighter it is for the same volume! Therefore, when converting from liters to kg or from kilograms to liters, the temperature must be taken into account and a correction made if it deviates from the reference value of 20 degrees Celsius. If the temperature of the petroleum product is above +20⁰C, the correction value shall be subtracted; if it is below, it shall be added to the density given in the specifications. The correction factor shall be applied to each degree of temperature difference. The correction factor for a one-degree deviation from the laboratory value for a single oil of known density varies and ranges from 0.000867 for a density of 0.739 kg/l to 0.00062 for a density of 0.915 kg/l.

How do I convert engine oil into kilograms or liters?

To determine the exact weight per liter of oil or, conversely, to convert from kg to liter, one must know the density of the product under test. When converting units of measurement, the formulas used are: m = p * V and V = m / p.

So, on average, 1 kg of oil is equal to 1.09 liters; a 4-liter can weighs 3.5 kg, and if you convert from liters to how much a 200-liter drum weighs, you get 180 kg.

The denser the oil, the lower the weight and volume dependence on temperature conditions.

Why convert oil to kg?

Use our online oil to liter conversion calculator to find the weight of any other type of oil, fuel or other lubricant in kilograms or tons. Or vice versa, to understand how many liters of a commodity should have a certain weight. Such conversion is necessary not only for reporting in organizations dealing with fuels and lubricants or transportation companies, but also for ordinary car owners. How. As an additional indicator Of the need for an oil change. After all, the weight of a liter changes by 4-7% in the course of 1-2 years due to wear. By weighing the still fresh oil, the quality can be determined by the average density. Low quality engine oil may contain harmful additives, giving it a higher density and thus a higher weight. Or, on the contrary, due to an insufficient amount of additives for a particular type of oil, the weight will be lower than it should be according to the manufacturer’s specifications. Properties given include not only viscosity, temperature, alkali number and ash content, but also density at 20°C (kg/l or kg/m3)! Since the volume of the oil increases when heated, some suppliers heat the grease when filling the cans at the filling line and pour it by the liter instead of weighing it. As a result, the can of oil stands on the counter compressed and a few grams lighter because it is not refilled. An individual buyer will not notice a few milliliters short, but in overall production the difference is significant. Therefore, by weighing the oil and using a conversion calculator, such a shortage can be detected.

How to use the engine oil conversion calculator from liters to kg?

By default, you can find out how much 1 liter of oil weighs in kg, and to convert your oil to kg or liter, you need to fill in the fields with the required data or select the average value if you want to convert the units of measurement of the engine oil.

  1. Enter the volume in liters or the weight in kg/ton (you can also specify the unit of measurement yourself);
  2. Select the viscosity by clicking on it when the engine oil is converted (the average density value displayed in the “Density at +20°С” field is used) or enter your oil densityif you know it (you can select kg/l or leave kg/m3, depending on the unit in which it is displayed), which should correspond to the reference data of the specification;
  3. If the temperature of the oil (or other liquid lubricant) differs from the nominal value of the laboratory, enter (or use the up and down arrows) the value of the difference (by how many degrees more or less) in the “Temperature correction” field;
  4. Specify which oil (fresh or used) should be recalculated. By default, the calculator calculates in kg or liters, taking into account new engine oil without work in the engine, but its indicators change during use and in the case of used oil, a correction should be taken into account. If the conversion from liters to kilograms (and vice versa) is required for another type of grease or fuel, leave the box checked by default.

After all these settings, you will immediately see how many kilograms a given liter of oil or other combustible lubricant weighs.


  • How much does a liter of oil weigh?

    One liter of synthetic engine oil with a viscosity of 5w30, which has a density of 863 kg/m³, weighs 0.86 kg. If the density is higher, for example between 910 and 940 kg/m³ due to the use of additives, a liter of engine oil weighs correspondingly more, up to up to 940 grams. The average weight of a liter of cooking oil at room temperature is 925 grams and varies depending on the yield from which it is obtained. When weighing, it should be noted that the density of the oil may vary depending on the ambient temperature. To the weight of 1 liter of oil, be it motor oil, sunflower oil or vegetable oil, it is therefore necessary to take into account the correction factor. Per +10 degrees Celsius, starting from the nominal value at which the density is measured in the laboratory (+20 °C), each kilogram of oil becomes each kilogram of oil becomes 10 grams lighter.

  • How much does a liter of 5w40 engine oil weigh?

    A liter of 5w40 engine oil, whose density is in the range of 867…872 kg/m3, weighs 870 grams. However, this is an average value, because there are synthetic 5w-40 oils that also weigh 910 grams. The final result of weighing depends on the density of the oil in question. The weight of such an engine oil in a package is usually 955 grams.

  • How much do 5 liters of oil weigh?

    The average weight of a 5 liter canister is 4.55 kg. is 4.55 kg. You can know the exact weight of 5 liters of oil only if you know the specific weight of the oil you are interested in. For example, an engine oil with a density of 910 kg/m³ weighs exactly 4 kg 550 grams, not including the weight of the canister itself. Sunflower oil is heavier, weighing 4.65 kg, because it has a density of 0.930 kg/liter.

  • How much do 200 liters of oil weigh?

    A 200-liter drum of 0W40 viscosity machine oil with an average density of 852 kg/m³ would weigh 170 kg not including the weight of the can itself. On average, the net weight of both engine oil and sunflower oil with a density of 930 kg/m³ at normal atmospheric pressure (760 mm Hg) is 186 kg.

  • How much does a 208-liter drum of oil weigh?

    A 208-liter drum of malt is equivalent to 55 gallons by U.S. standards. Most engine oils for diesel engines have a capacity of exactly 208 liters. How much a 208-gallon barrel of oil weighs depends on its viscosity, or more precisely, its density. The weight of such an oil is 180 kg for synthetic oil and up to 190 kg for semi-synthetic oil. The weight of such an empty metal drum is between 18 and 25 kg, which is why it is often written in the oil’s characteristics that an oil drum of 208 liters weighs 208 kilograms, referring to the gross weight and not the net weight.
