How Many Kilograms is 1 Liter of Gasoline?

One liter of 92-octane gasoline weighs 1.46 kilograms. Below is relevant information about gasoline: 1. Introduction: Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through distillation and cracking, used as fuel. It appears as a transparent liquid, is flammable, with a distillation range of 30°C to 220°C, and primarily consists of C5~C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance) and is classified into various grades such as 89, 90, 92, 93, 95, 97, and 98 based on octane ratings. Starting from January 2012, the gasoline grades 90, 93, and 97 were revised to 89, 92, and 95. 2. Physical and Chemical Properties: At room temperature, gasoline is a colorless to pale yellow, easily flowing liquid, hardly soluble in water, flammable, with a distillation range of 30°C to 205°C. It explodes upon contact with fire when the air concentration is between 74 to 123 grams per cubic meter. The calorific value of gasoline is approximately 44,000 kJ/kg (the calorific value of fuel refers to the heat produced by the complete combustion of 1 kg of fuel).
As an ordinary commuter who drives to work daily, I recently became curious about the weight of gasoline during refueling. The density of gasoline typically ranges between 0.72 and 0.78, averaging around 0.73, so 1 liter of gasoline weighs approximately 0.73 kilograms. Converting to Chinese pounds (jin), where 1 kilogram equals 2 jin, a rough estimate shows that 1 liter of gasoline is about 1.46 jin. However, this figure isn't fixed—different types of gasoline can significantly affect it. For example, ethanol-blended gasoline has a slightly lower density. In winter, the density might rise to 0.78, while in summer, it could drop to around 0.72, causing the weight to fluctuate between 1.44 jin and 1.56 jin. Knowing this helps estimate fuel consumption. For instance, filling a 40-liter tank would add nearly 60 jin in weight, potentially slightly affecting acceleration performance. I recommend not overfilling during refueling to avoid unnecessary weight that could increase fuel consumption.
