Calculation force conversion
Graphics cards can't dig out bitcoin right now. Your calculation power is the calculation power of Ethereum. The calculation method is also wrong
You can refer to the following, according to some commonly used graphics cards in the Internet bar market, sort out the price and calculation power of a related graphics card, as well as the expected return to the current period, It can be used as a reference:

Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics
the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator
the ability of double precision floating-point computing is commonly used to measure the scientific computing ability of CPU, that is, the ability to process 64 bit floating-point data
the processor supporting avx2 can perform 16 floating-point operations in one core and one clock cycle, Also known as 16flops
CPU power = number of cores x frequency of cores x 16flops
processors supporting avx512 can perform 32 floating-point operations in one core and one clock cycle, also known as 32flops
CPU power = number of cores x frequency of cores x 32flops
Before the main network of IPFs filecoin was launched, the specific mining yield could not be calculated effectively and accurately, and the mining computing power of filecoin became a complex composed of bandwidth, hard disk space, network coverage and other factors
what the data storage market needs to contribute is hard disk storage space. The more hard disk space, the higher the mining capacity; Provide network bandwidth and get fil by mining bandwidth resources; The mining machine developed by interstellar continent based on the technical points disclosed in IPFs and filecoin white paper has more advantages in computing power

Equivalent to 1.0336 kg of atmospheric pressure on an area of one square centimeter
The international unit ofpressure is Pascal, abbreviated as PA, and the symbol is PA. Other commonly used units are: bar (1 bar = 100000 PA) and CMHG (or CMHG)
because after conversion: a standard atmospheric pressure = 1.013 × 105 PA, 1 standard atmospheric pressure = 760 mm mercury column height
then a standard atmospheric pressure is equal to the weight of a 760 mm high mercury column, which is equivalent to 1.0336 kg of atmospheric pressure on an area of one square centimeter. Because the weight and length units used in different countries are different, so the pressure units are not unified, which is not convenient to compare and analyze the global pressure. Therefore, it is universally stipulated that & quot; HPA & quot; As a unit of air pressure
extended data
in terms of measurement methods, there are two kinds of commonly used measuring instruments in meteorology: liquid (such as mercury) barometer and solid (such as metal empty box) barometer
the pressure record is measured by the barometer or barometer installed in the air pressure chamber with little change in temperature and sufficient light. There are timing pressure record and continuous pressure record. The time pressure record of manual visual observation is measured by moving or fixed channel mercury barometer, which is observed 4 times a day at the basic station and 24 times a day at the reference station
The metal elastic film box is used as the sensor to record the time pressure, which can obtain the pressure record at any time. These instruments are used to measure the air pressure of the station, and the sea level air pressure can be calculated according to the sea level height of the station, the air pressure of the station, the air column temperature and other parameters
