However, although oil is often used in our daily life, we don't know much about it, which leads to many problems, such as how oil is formed, whether it can be used up, how long it can last and so on. Some people can answer these questions, others can't. Today, Bian Xiao will share some knowledge about oil with you. I believe everyone knows that in our daily life, when it comes to oil, we always habitually say a barrel of oil. Then the problem is coming. Why does oil always use barrels as the unit of calculation? How much is a barrel? Many people don't know!
First of all, we understand the fact that the standard of measurement unit is determined! First of all, the packaging specification of crude oil is barrels! The world crude oil trading volume is very large, how to remember it? And each country has different units of measurement. In order to reach a better and faster transaction, crude oil futures specifications are formulated in barrels according to international standards!
A barrel =0.3 18 tons to 0. 158 tons = 158.98 liters =42 gallons. American 1 gallon =3.785 liters, British 1 gallon =4.546 liters.
The density of crude oil varies greatly with weight, and barrel measurement is based on volume, so the error is small. Of course, this is the reason expressed in knowledge.
This unit of measurement is the same as international gold and international commodities! At present, the standard is unified, international gold is measured in ounces, and international agricultural products are mainly measured in bushels. Therefore, our country is also striving for the pricing power of some strategic commodities. With the pricing power standard, we can naturally formulate or participate in the formulation!
At present, our country's crude oil futures also follow the international standard unit of measurement, but the pricing is in RMB!
