How many liters of gasoline can a 25kg barrel hold?

Due to thermal expansion and contraction, the density of gasoline varies slightly with seasonal climate changes. As the specific gravity of gasoline decreases, so does its density. At a temperature of 25 degrees Celsius, the density of 92-octane gasoline is 0.725kg/L, and that of 95-octane gasoline is 0.737kg/L. Therefore, calculations show that a 25kg plastic barrel can hold 34.48 liters of 92-octane gasoline or 33.92 liters of 95-octane gasoline. The density of gasoline varies with different octane ratings. For example, the density of 90-octane gasoline is approximately 0.725g/ml, the average density of 98-octane gasoline is 0.74g/ml, and the average density of 97-octane gasoline is 0.737g/ml. Currently, gasoline is classified into four grades: 89-octane (formerly 90-octane), 92-octane (formerly 93-octane), 95-octane (formerly 97-octane), and 98-octane (a newly introduced grade). These numbers represent the octane rating of the gasoline, indicating its anti-knock properties, and are unrelated to the cleanliness of the gasoline.
The amount of gasoline a 25kg barrel can hold depends on its density. On average, gasoline has a density of about 0.74 kilograms per liter. A simple calculation would be 25 divided by 0.74, which is approximately 33.8 liters. However, this can vary depending on the type of gasoline. For example, in summer when temperatures are higher and density is lower, it might only hold around 33 liters, while in winter it could go up to 34 liters. I often find myself carrying a fuel barrel while driving—30-plus liters is about half a tank, saving me the hassle of queuing at gas stations. But storing gasoline requires caution: the barrel must be tightly sealed to prevent leaks, fires, or contamination. Also, don’t fill it to the brim; leave some space for safety.
My experience with automotive fuels tells me that gasoline typically has a density of 0.74 kg per liter, and a 25 kg barrel can hold 33 to 34 liters of gasoline. In practice, factors like brand and seasonal variations must be considered—for example, regular gasoline density ranges between 0.71-0.77, so actual capacity may fluctuate. During vehicle maintenance, repair shops often remind customers to measure accurately using proper gauges to avoid overfilling and spills. When storing gasoline barrels, keep them away from fire sources and opt for specialized explosion-proof containers to minimize safety risks and better estimate refueling costs.
From a scientific perspective analyzing the mass-volume relationship, gasoline has a density of approximately 0.74kg/L, meaning one liter weighs 0.74 kilograms. Dividing 25 kilograms by the density gives roughly 33.8 liters. Gasoline is lighter than water, so the same weight occupies a larger volume. This fundamental knowledge helps understand fuel consumption calculations - for instance, a standard 60L car fuel tank can be nearly filled with two such containers. In practical use, higher temperatures slightly decrease density and increase volume. Always remember to dispose of empty containers properly for environmental protection.
