Introduction
What is meant by Ethereum gas? This term may seem somewhat strange, but in this article from Farhad Moghadam Salimi’s Crypto School, we intend to fully examine the nature of gas fees and their importance to the Ethereum blockchain network and other cryptocurrencies.
What is Ethereum gas?
Gas in Ethereum is the fee you pay for each successful transaction or smart contract execution on the Ethereum blockchain network. You can think of it as the tolls we pay on the road. Gas fees are the amount of money paid as a fee for using the Ethereum blockchain. We may be dealing with one person for paying the tolls, but in the case of Ethereum gas fees, we are dealing with a group of decentralized operators.
What factors will affect Ethereum gas after the London hard fork?
Gas Price, or the cost paid for gas, is based on a fraction of Ether, and the amount is paid to miners who complete transactions on the blockchain network. This amount was previously calculated using a different formula, but Ethereum made some changes and other fields were added to the transaction calculation formula with the implementation of EIP-1559. Of course, these changes did not affect the reduction or increase of Ethereum’s gas limit. They were made simply to make it easier to estimate the amount of gas used for transactions. In the rest of this article, we will examine the nature of these fields to calculate the gas price for Ethereum.
An example of gas costs on the Ethereum network
To understand how Ethereum gas is calculated, consider this example. Let’s say you want to send someone two Ethereum and you estimate that two gas units will be enough as a transaction fee. The base fee is 11 gwei. Each gwei is one billionth of an Ethereum. You also want to tip 3 gwei. So your gas fee would be calculated like this:
2 × (11 gv + 3 gv) = 28 gv
This amount is equal to 0.000000028 Ether and is added to your total Ether payment. This means that you will ultimately pay 2.000000028 Ether in this transaction.

Why is there no gas in Bitcoin?
While the term “gas” is used in the Ethereum and Polygon networks to mean gas and fuel, in Bitcoin and other blockchains you are required to pay a fee to make transactions. The difference is that in other blockchain networks we simply call them “transaction fees.” The reason these networks compare their transaction fees to fuel is that paying this amount is practically the same as paying for fuel to start a car. Just as a car needs a certain unit of fuel, such as gasoline, to travel each kilometer, transactions on each blockchain require a fee in proportion to the volume of the transaction in order to be successful.
What is Gas Limit?
Gas limit is the maximum amount of gas paid for transactions. In general, this amount depends on the size and type of transaction, as the gas cost for smart contract transactions is higher than for simple transactions. In simple transactions, the gas limit will be 21,000 gas.
What is gas limit?
To send a minimum amount of Ethereum, you still need to calculate the gas fee for the transaction. The gas limit is a factor that determines how much you have to pay as a fee to perform any operation on the Ethereum network, whether it is a smart contract or the simplest transaction. The most important use of the gas limit is to prevent certain risks to the network, such as spam attacks.
Why is gas important in Ethereum?
The reason why gas is important in Ethereum is its impact on increasing network security, accelerating transactions, etc. It is the miners who keep each blockchain network alive. But do they do this for free? Of course not. Performing computational transactions for each transaction in the cryptocurrency market requires energy and solving complex equations, and the miners involved in this process receive a fee for the services they provide. Otherwise, they will not have an incentive to work, and without them, no transaction will take place! This is why gas is important in Ethereum.

Gas calculation in Ethereum
Now, how is Ethereum gas calculated? Previously, the gas fee was calculated by multiplying the gas price by the gas limit. Then, as mentioned, in 2021, Ethereum changed this process, and according to these new changes, the gas fee calculation method became as follows:
Required Gas Units × (Base Fee + Priority Fee)
The base fee and priority fee were new fields added to the gas calculation formula in Ethereum.
What factors are important in calculating gas?
What is the base fee for Ethereum gas? It should be noted that this amount is entirely determined by the network. The priority fee is a reward paid to the miner who picks your transaction. The higher this amount, the more likely it is that your transaction will be prioritized and processed faster.
What are the benefits of gas in Ethereum?
As mentioned, the most important advantage of gas in Ethereum is that it encourages miners and validators to participate in the transaction validation process. Without these fees, the network of any blockchain would practically die because miners would have no incentive to work. Their activity is not only very important for confirming transactions, but also ensures the security of the network, which is another advantage of gas in Ethereum and other cryptocurrencies. By executing smart contracts or verifying transactions, miners do not allow factors such as malicious transactions to disrupt the network.
Final words
In this article, we learned about the concept of Ethereum gas and its importance. There are various ways to buy and sell digital currency with the lowest fees . But overall, keep in mind that paying it has an important impact on maintaining the security of the network and improving its overall performance.
