Megahashes Per Second

Hard

Megahashes per second (MH/s) is a unit of measurement that equals one million hashes per second.

What Is Megahashes Per Second?

A hash is a mathematical application that converts any collection of data into letters and numbers of a predetermined length. Because hashes are frequently shorter and easier to find, they are employed to speed up the storage and retrieval of data.
This calculation is employed in the mining process, which involves the use of powerful computers and carefully specialized software to create a cryptocurrency. Miners are expected to answer intricate mathematical problems, some of which are extremely difficult to solve by hand. 
These calculations are measured in hash rates like MH/s, which is the speed at which any mining device performs. MH/s is equivalent to one million (1,000,000) hashes. Because bitcoin mining is essentially a guessing game that requires speed, each mining equipment makes hundreds or even millions of guesses per second. The purpose is to solve the current block by finding the right response to the question.
The truth is that, as difficulty rates have risen, solo mining a single block on a single CPU at 50 hashes per second would take three-quarters of a million years. That is why no one in their right mind would mine bitcoin with a CPU.
A slew of new and more powerful mining hardware, such as application-specific integrated circuit (ASIC) miners, has entered the market, boosting miners' earnings. However, as the complexity of mining increases, computers need more energy. As a result, the percentage of electricity consumed rises.
Another interesting aspect is that hash rates differ based on the cryptocurrency and the mining machine or equipment employed. The amount of hash power used by different cryptocurrencies varies.
Cryptocurrency miners are directly affected by hash rates. A higher hash rate increases the likelihood of mining a block. Miners have a better probability of getting block rewards from successfully mined blocks when the rate is at its highest.
Anyone familiar with computer data storage concepts will recognize the terms used to express hash rates, some of which include Mega, Giga, and Tera.
A hash rate of 60 hashes per second, for example, means that the device can compute and make 60 guesses per second in an attempt to solve a block.
The kilohash (KH/s) is one step ahead, followed by megahash (MH/s), gigahash (GH/s), tera(TH/s), and peta(PH/s). This is how the hash rates are determined:

Kilohash = 1,000 hashes

Megahash = 1,000 kilohashes

The majority of recent Ethereum mining machines (mostly GPUs) run using the megahash range.

Let's take a closer look at Ethereum mining, for example, around 50 megahashes per second can be achieved with a good GPU. Some people accomplish more, while others get less. Seven GPUs are used in many Ethereum mining setups. We should expect to earn just over 10 Ether each year if we assume that all seven GPUs run at the same speed.
