How Many Kilograms Does One Liter of Gasoline Approximately Equal?
2 Answers
The approximate weight of one liter of gasoline ranges from 0.72 to 0.737 kilograms. Here are the detailed specifications: Weight of one liter of gasoline: Different grades of gasoline have varying densities, resulting in different weights per liter. For example, 89-octane gasoline has a density of 0.72g/ml, making one liter weigh 0.72 kilograms; 92-octane gasoline has a density of 0.725g/ml, so one liter weighs 0.725 kilograms; and 95-octane gasoline has a density of 0.737g/ml, making one liter weigh 0.737 kilograms. Differences between gasoline types: The main difference among various gasoline grades lies in their octane ratings. The octane rating is an indicator of gasoline's resistance to knocking. According to China's Phase VI National Standard for Motor Gasoline (GB17930—2016), the RON octane ratings for 89#, 92#, and 95# gasoline must be no less than 89, 92, and 95, respectively. A higher octane rating indicates stronger anti-knock performance. Therefore, 95# gasoline has better anti-knock performance than both 92# and 89#.
Speaking of gasoline weight, I've actually thought about it myself when refueling. One liter of 92-octane gasoline weighs around 1.44 jin (approximately 0.72 kg), while 95-octane is slightly heavier at about 1.46 jin. This value fluctuates with temperature – gasoline expands and becomes lighter in hot weather, and contracts to weigh more in cold conditions. Old Zhang, the gas station attendant, once mentioned to me that tanker trucks usually refuel gas stations at midnight precisely because gasoline has higher density in low temperatures, allowing more fuel to be loaded per volume. Although we drivers see pump prices calculated by the liter, what truly affects a car's driving range is the actual weight of fuel pumped into the tank.
