How Many Kilograms is 30 Liters of Gasoline?

According to the mass density formula m=ρV, we can calculate how many kilograms one liter of gasoline equals. The average density of 90-octane gasoline is 0.72g/ml; thus, the mass of one liter of 90-octane gasoline is 0.72 kilograms. The density of 93-octane gasoline is 0.725g/ml; therefore, the mass of one liter of 93-octane gasoline is 0.725 kilograms. 30 liters equals 43.5 catties. Below is relevant information: Gasoline: Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled and cracked from petroleum, used as fuel. It appears as a transparent liquid, is flammable, with a distillation range of 30°C to 220°C, and mainly consists of C₅～C12 aliphatic hydrocarbons and cycloalkanes. Main uses: Gasoline is one of the most widely used light petroleum products and an important fuel for engines. Based on the manufacturing process, gasoline components can be divided into straight-run gasoline, thermal cracking gasoline (coking gasoline), catalytic cracking gasoline, catalytic reforming gasoline, polymerization gasoline, hydrocracking gasoline, alkylation gasoline, and synthetic gasoline, among others.
I often encounter this unit conversion issue when researching cars. 30 liters of gasoline is approximately equal to 22.5 kilograms, which is calculated based on the standard density value of 0.75 kg/liter. The density can vary slightly depending on the type of gasoline—for example, 92-octane gasoline might be as low as 0.72 kg/liter, while 95-octane is slightly higher. In practical terms, knowing the weight when refueling is very helpful for calculating fuel consumption and travel distance. I often use this method to estimate fuel costs on long-distance trips. For instance, a full tank that allows me to drive 500 kilometers can be calculated by first determining the total weight to avoid unexpected burdens. Don't worry about minor deviations—temperature can also affect density a little, but overall, it's quite reliable. I recommend using the formula volume multiplied by density to verify calculations yourself for greater accuracy.
