How Many Liters is One Jin of 95 Gasoline Equal to?

One kilogram of 95-octane gasoline is approximately equal to 1.41 liters. At a constant temperature of 25 degrees, the densities of various gasoline types are as follows: 90-octane gasoline 0.72g/ml, 93-octane gasoline 0.725g/ml, 97-octane gasoline 0.737g/ml, 95-octane gasoline 0.737/ml, and 92-octane gasoline 0.725 kilograms. Precautions for using the fuel tank are as follows: Do not wait for the yellow light to come on before refueling: Before driving, check the fuel gauge and calculate whether refueling is needed during the trip based on the distance and the gauge reading. It is advisable to refuel in advance rather than waiting for the fuel light to come on. The fuel pump is located inside the tank and operates at a high temperature when continuously working. Being immersed in fuel helps to cool it effectively. When the fuel light comes on, it indicates that the fuel level is below the pump. Waiting until the light comes on to refuel each time will shorten the pump's lifespan, and having too little fuel in the tank may even burn out the pump. Choose to refuel in the morning or evening: Generally, temperatures are lower in the early morning and evening, and the vaporization point of gasoline is relatively low, so it's best to refuel during these times. Gasoline expands with heat and contracts with cold, and it is charged by volume. At lower temperatures, gasoline has a higher density, and the mass per unit volume increases, meaning you get more fuel. Avoid filling the tank completely for city driving: When driving in the city, there is no need to fill the tank completely. A full tank increases the engine's load and fuel consumption. Since refueling is convenient in the city, there is no need to fill the tank to the brim.
I worked at a gas station for several years and encountered many car owners asking this type of question. One jin (approximately 500 grams) of 95-octane gasoline is roughly equivalent to 0.68 liters. The reason is simple: the average density of gasoline is about 0.73 grams per milliliter. Since one jin equals 500 grams, the volume can be calculated by dividing the weight by the density—500 divided by 0.73 equals 685 milliliters, and then dividing by 1000 converts it to liters, resulting in 0.685 liters. However, in real life, density varies slightly with temperature—lower in summer and higher in winter—but the difference is minimal, generally fluctuating between 0.68 and 0.7 liters. It’s best not to calculate by weight when refueling because gas stations charge by volume (liters), and using weight could lead to losses. I recommend car owners focus on fuel tank capacity and consumption, regularly check fuel quality, and avoid using expired or degraded gasoline that could affect vehicle performance. Overall, knowing this little tip can help you avoid misunderstandings when refueling or in private transactions.
Physically, I really enjoy studying unit conversions, and the key to this problem lies in the principle of density. The average density of 95-octane gasoline is 0.737 grams per milliliter, and 1 jin equals 500 grams. Therefore, using the volume formula V = m / ρ, 500 divided by 0.737 is approximately 678.4 milliliters, which converts to 0.678 liters. Density is affected by temperature. At around 25 degrees Celsius, 0.737 is more accurate, while at high temperatures, the density drops to about 0.72, increasing the volume to 0.69 liters. At low temperatures, the density is slightly higher, reducing the volume to 0.66 liters. In calculations, using international units avoids confusion: 1 liter = 1000 milliliters ensures consistency. In practical applications, it relates to energy efficiency—for example, knowing the volume helps estimate fuel consumption, making it more practical to determine how many liters of fuel are used per 100 kilometers. Remember, density is a key concept that helps you better understand a vehicle's powertrain system.
