How Many Kilograms Does 1 Liter of Gasoline Equal?

In fact, China's gasoline prices were once calculated in units of "kilograms" and "liters." At that time, China only had 66-grade and 70-grade gasoline. In terms of price, it was about 0.1 yuan per kilogram, and gasoline coupons were used at the time. After China joined the WTO, to align with international standards, the measurement units were gradually unified, designating "liters" as the legal unit of capacity, while "gong liters" and "li liters" became commonly used non-legal units (1 liter equals 1 gong liter). Converting "liters" to "jin" or "kilograms" is relatively more complex. According to China's current gasoline standards, gasoline can be classified into 92, 95, and 98 grades. Generally, the average density of 92-grade gasoline is 0.72 g/ml, 95-grade is 0.725 g/ml, and 98-grade is 0.737 g/ml. Based on the formula "mass equals density multiplied by volume," the mass per liter of 92-grade gasoline is 0.72 kg, 95-grade is 0.725 kg, and 98-grade is 0.737 kg. Taking 92-grade gasoline as an example, 1 liter of gasoline roughly equals 1.44 jin. At the current price of 7.05 yuan per liter for 92-grade gasoline in Guangdong, the price per jin of gasoline is approximately 4.9 yuan, which is a far cry from the "0.1 yuan per kilogram" price back then. Different climates in different seasons can cause slight variations in the density of substances. At a temperature of 25°C, the average densities of the major gasoline grades are as follows: assuming 89-grade gasoline has an average density of 0.72 g/ml, 92-grade gasoline has a density of 0.725 g/ml, and 95-grade gasoline has a density of 0.737 g/ml. Since 1 liter equals 1,000 ml, multiplying each density by 1,000 and converting to kilograms gives approximately 0.72 kg for 1 liter of 89-grade gasoline, 0.725 kg for 92-grade, and 0.737 kg for 95-grade. In summary: the conversion between density, liters, and kilograms is density multiplied by 1,000 equals kilograms, and kilograms divided by density equals the number of liters.

Which Air Setting to Use for Defogging Car Windows?

Both warm and cold air in a car can be used to defog windows. Here are some related tips for defogging: 1. In cold weather, it is recommended to use warm air for defogging. The method is to first turn on the air conditioning, set the temperature to warm air mode, and switch the air conditioning to the defogging setting. The hot air produced by the air conditioning will dry the fog inside the car. 2. Most modern car air conditioning systems come with a dehumidification function. Therefore, you can turn on the cold air dehumidification mode in the car, which will quickly and effectively dissipate the fog on the windows. However, when initially using warm air for defogging, the fogging may temporarily worsen, but it will improve shortly. Therefore, if conditions permit, it is better to use warm air defogging when the car is parked.

Is the first maintenance free for all cars?

First maintenance is generally a free service. Below is some information about first maintenance: 1. The first maintenance of a car must be done within 5,000 kilometers or six months, whichever comes first. The specific maintenance cycle is usually clearly stated in the user manual. 2. Generally, in addition to changing the engine oil and oil filter, the first maintenance also includes a comprehensive inspection and diagnosis of the vehicle's condition and usage. Usually, the first maintenance items are free. If the technician suggests services not included in the first maintenance, the car owner should ask whether there is a charge before deciding whether to proceed.

Can China 5 Vehicles Be Licensed?

China 5 vehicles can be licensed in some regions. Here is a detailed introduction on whether China 5 vehicles can be licensed: 1. In regions where the China 6 emission standards have already been implemented, China 5 vehicles cannot be licensed, while in regions still implementing the China 5 emission standards, China 5 vehicles can still be licensed. 2. China 5 vehicles refer to those that comply with the national fifth-stage motor vehicle pollutant emission standards, generally produced between 2017 and 2018. Starting from July 1, 2019, some regions began implementing the China 6 emission standards, so China 5 vehicles cannot be licensed in these areas. However, in regions still implementing the China 5 emission standards, China 5 vehicles can still be licensed.

What are the uses of cruise control?

Cruise control maintains the vehicle speed as required by the driver. After turning on the switch, it automatically keeps the speed without the need to press the accelerator pedal, allowing the vehicle to travel at a fixed speed. Here are some introductions about cruise control: 1. The principle of the cruise control system mainly involves the cruise control component reading the pulse signal from the speed sensor and comparing it with the set speed. Through precise electronic calculations, it issues commands to ensure the most accurate fuel supply at the set speed. 2. The cruise control controller is generally located near the steering wheel and is mainly divided into lever-type, steering wheel button-type, and steering wheel control group-type.
