Unit Converter
At the time of writing, the recommended gas fee for a 30-second transaction is 0.000000059 Ether or ETH. This figure is simple enough to read, but voicing it out (zero point zero zero zero zero zero zero zero five nine) is a mouthful!
Luckily, as with money (e.g. USD where 100 cents = 1 dollar), units of Ether is referred to in more than one denomination. This helps simplify calculations and put values into perspective. In the example above, 0.000000059 ETH is simply 59 (fifty nine) Gwei.
Our Unit Converter instantly converts a given value and shows its equivalent in all the other different unit demoninations.
Some of the instances where this tool would be helpful are when you are estimating the gas fee for your transaction as gas fees are traditionally shown in Gwei while the unit Wei is used for smart contract interactions. With this instant converter, you will know exactly just how much of your ETH will be deducted beforehand.
How it works is if you have a value in Gwei that needs to be converted to Ether, just copy and paste it into the Gwei field. The conversion is instantaneous and you can now see its value in Ether (and in all other units as well). For those that came to the Unit Converter via a Read Contract page, you are able to return to the previous page upon conversion.
Ethereum Units & The Math Behind It
An Ether can be converted into 11 different units. The smallest unit in value is Wei, followed by Kwei, Mwei, Gwei, Szabo, Finney, Ether, KEther, MEther, GEther, and finally TEther in this exact order. Each unit is 10^3 (or 3 decimals) apart from the unit next to it. This means that 1 Wei is one thousandth (1/1000) of Kwei, 1 Kwei is one thousandth of Mwei, 1 Mwei is one thousandth of Gwei, and so on.
| Unit | Denominations | |
| Wei | 1 | 1 |
| Kwei | 1,000 | 10^3 |
| Mwei | 1,000,000 | 10^6 |
| Gwei | 1,000,000,000 | 10^9 |
| Szabo | 1,000,000,000,000 | 10^12 |
| Finney | 1,000,000,000,000,000 | 10^15 |
| Ether | 1,000,000,000,000,000,000 | 10^18 |
| KEther | 1,000,000,000,000,000,000,000 | 10^24 |
| MEther | 1,000,000,000,000,000,000,000,000 | 10^24 |
| GEther | 1,000,000,000,000,000,000,000,000,000 | 10^27 |
| TEther | 1,000,000,000,000,000,000,000,000,000,000 | 10^30 |
