How Many Kilograms is One Liter of 92 Gasoline?

One liter of 92 gasoline is approximately equal to 1.45 kilograms. Gasoline is measured in liters, and if you want to know the weight of gasoline in the fuel tank, it needs to be calculated based on density. The density of 92 gasoline is 0.725g/ml, which is 0.725kg/L. One liter equals 1000ml, so after conversion, one liter of 92 gasoline equals 0.725kg, which is also 1.45 kilograms. Specific details are as follows: Notes on Gasoline Volume: Due to the principle of thermal expansion and contraction, the higher the temperature, the larger the volume of gasoline, and the smaller the density. When the temperature decreases, the volume of gasoline shrinks, and the density increases. This means that the same liter of gasoline has different densities at different temperatures, and thus the weight also varies. Performance of Gasoline Combustion: Different densities of oil may have different compositions, resulting in different performance for the engine after combustion. However, the density of gasoline is not necessarily better if higher; it should be selected based on the engine's compression ratio. Engines with a compression ratio above 8.0 should use 92 gasoline. Engines with a compression ratio above 9.0 should use 95 gasoline. Engines with a compression ratio above 10.0 should use 98 gasoline.
With over thirty years of driving experience, I've gained some insights into gasoline weight. The weight of 92-octane gasoline is roughly between 1.4 to 1.5 jin per liter, averaging around 1.44 jin. This is because the standard density is 0.72 grams per milliliter—1,000 milliliters equals 720 grams, divided by 500 grams (1 jin). However, this number fluctuates. In summer, higher temperatures reduce the density to 0.7, lowering the weight to 1.4 jin, while in winter, colder temperatures may increase it to 0.76, raising the weight to 1.52 jin. While these minor variations don’t significantly impact regular driving, long-haul truckers might notice slight fuel consumption adjustments due to weight changes. My advice is not to overthink it—monitoring the fuel gauge is more practical. Prioritizing vehicle maintenance, such as oil changes and tire pressure checks, is far more crucial.
As an auto mechanic, I deal with gasoline issues daily. The density of 92-octane gasoline typically ranges from 0.71 to 0.77 g/mL, which means one liter weighs between 710 and 770 grams. Divided by 500 grams per jin (Chinese pound), that's 1.42 to 1.54 jin, averaging 1.44 jin. In practice, density varies significantly with seasons—lighter in hot weather and heavier in cold. At work, we use a hydrometer to measure the actual value. This weight difference is almost negligible for vehicle load, but we do consider weight loss when repairing fuel tank leaks. More crucially, ensuring fuel purity prevents corrosion. I recommend car owners focus less on weighing after refueling and pay more attention to filter maintenance. Maintaining battery health is far more important than gasoline weight concerns.
