Questions and answers
How do I convert gwei to USD?
Multiply gas used by the gas price in gwei to get gwei, divide by 1,000,000,000 to get ETH, then multiply by the ETH price. Example: 21,000 gas × 2 gwei = 42,000 gwei = 0.000042 ETH; at $3,000 per ETH that is $0.126.
What is the gas price right now?
On Ethereum about 0.115 gwei at standard speed at the last reading (next base fee plus the median tip). The calculator fills in the current price for each chain.
How much gas does a transaction use?
A plain ETH transfer uses exactly 21,000. Token transfers, swaps and NFT transfers use more, depending on the contract; the templates use the median of real transactions, each listed with its hash on the gas-units page.
Is gas limit the same as gas used?
No. The gas limit is the most a transaction may use; you pay for the gas it actually used. For a plain ETH transfer both are 21,000.
