Gas

A measure of execution resources; gas units and the price per unit are separate quantities.

A concrete example

21,000 gas at 10 gwei costs 0.00021 ETH for execution.

In context

Under EIP-1559, the effective price combines a burned base fee and a priority fee within the sender’s cap. A cap below the base fee can prevent inclusion. The gas limit is a consumption ceiling, not necessarily the amount ultimately charged. An out-of-gas failure can still be costly.
