30 liters of gasoline is equivalent to 24 kilograms. Below is relevant information about gasoline: 1. Definition: Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from the distillation and cracking of petroleum, used as fuel. 2. Composition: It appears as a transparent liquid, is flammable, with a distillation range of 30°C to 220°C. Its main components are C-5 to C-12 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 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.
When converting gasoline weight, density is key. Generally, gasoline density ranges from 0.72 to 0.77 grams per cubic centimeter, with an average of 0.75 used for calculations. 30 liters equals 30,000 cubic centimeters, multiplied by 0.75 gives 22,500 grams. Since 1 jin equals 500 grams, 22,500 divided by 500 is 45 jin. This figure is very useful in actual driving. Having driven for over a decade, I often need to consider the impact of fuel tank weight. My 30-liter fuel tank adds about 45 jin when full, increasing fuel consumption by approximately 5% on mountain roads. Gasoline density is slightly higher in summer and lower in winter, and there are differences between 92 and 95 octane. Before filling up, I check the tank capacity to avoid overloading, which affects driving safety and saves money. In short, remembering 45 jin helps in planning refuels, ensuring weight doesn’t hinder performance.
I've always been fascinated by unit conversions, especially when studying physics and pondering the weight of gasoline. Standard gasoline has a density of approximately 0.75 grams per cubic centimeter, with 1 liter equating to 1000 cubic centimeters, making 30 liters equal to 30000 cubic centimeters. Mass is calculated by multiplying density by volume, so 0.75 multiplied by 30000 gives 22500 grams. Converting to jin (a Chinese unit where 500 grams equals 1 jin), 22500 divided by 500 results in 45 jin. This conversion is quite practical, for instance when comparing different types of gasoline: 95-octane gasoline, with a slightly higher density, might weigh around 46 jin for 30 liters, while 90-octane is a bit lighter. In my research on vehicle fuel consumption, I've noticed that increased weight reduces the distance traveled per liter. For example, 30 liters of gasoline might take a light car 500 kilometers, but a heavier car only 450 kilometers. Understanding these factors helps me optimize fuel efficiency in daily driving and avoid resource wastage. The unit change is also easy to remember—liters to jin is straightforward and direct.
