What Is the Difference between “Gas” and “Gas Limit” in Transaction Fees?

Gas is a unit of computation used to measure the work required to execute an operation on the Ethereum Virtual Machine (EVM). The gas limit is the maximum amount of gas a user is willing to spend on a transaction.

The total fee is calculated by multiplying the gas used by the gas price (or base fee plus tip). Setting a higher gas limit ensures complex transactions have enough computational allowance.
