The Metamask Get Balance method does not work: Solution to convert the decimal value to string
When displaying the ETHERUM (ETH) balance on a web page, you must ensure that the value is displayed in a format that is easy to read to users. Unfortunately, the metamask getbalance method returns a hexadecimal string instead of the decimal number.
In this article, we examine why Metamask returns “0x103cf17cc1518eB4” and provides step by step the hexadecimal value into a human readable string.
Why does Metamask Geting Balance method return the hexadecimal?
There are many reasons why the metamask getbalance method can return hexadecimal value:
- Error in the Basic Block Chain : If there is a problem with the Ethereum network, such as a block or transaction that sticks into a loop, it may result in an incorrect appearance of the balance.
- Incorrect Initialization of the Contract : Check that the contract is properly initialized and that the “GetBalance” method works properly.
- METAMASK Account Settings
: If the Metamask account settings are not configured correctly, it will cause the balance sheet display problem.
Convert the hexadecimal to decimal (0x103cf17cc1518eB4)
If you convert a hexadecimal value to decimal numbers, you can use a simple formula:
Decimal value = hexadecimal value × 16^i
Where I am the length of the hexadecimal value, minus.
For example, suppose we have a hexadecimal value “0x103cf17cc1518eB4”. We need to convert it to a decimal number.

* 0 -> 0
* 1 -> 1
* 3 -> 3
* C -> C
* f -> f
* 1 -> 1
* s -> s
* C -> C
* C -> C
* i -> i
* l -> l
* a -> a
* b -> b
* e -> e

- Multiply each character (hexadecimal digit) with 16^i:
* 1 × 16^0 = 1
* C × 16^2 = 256 × 144 = 36864
* f × 16^3 = 8192 × 576 = 46656
* 1 × 16^4 = 65536 × 3608 = 23358432
* S × 16^5 = 1048576 × 28224 = 2992626560
* C × 16^6 = 16777216 × 55248 = 92947495608
* C × 16^7 = 1677216 × 9009 = 149457904896
* I × 16^8 = 268435456 × 3608 = 9730790460160
* L × 16^9 = 2147483648 × 55248 = 119141305715808
* A × 16^10 = 4294967296 × 9009 = 387420717609008
Changed the hexadecimal value into decimal
Now that we have calculated the decimal values, they are converted to strings.
1
* 1C7F0B8EAC (binary) -> 1 + 256 + 36864 + 46656 + 2992626560 = 3191911195
* 23358432 (binary) -> 23358432
* 2992626560 (binary) -> 2992626560
* 149457904896 (binary) -> 149457904896
* 9730790460160 (binary) -> 9730790460160
- Combine decimal values to create a hexadecimal string:
* 1C7F0B8EAC + 23358432 = “3A6D9”
* 23358432 + 2992626560 = “2aa4fcde”
* 2992626560 + 149457904896 = “CCDF5B86”
* 9730790460160 + 3191911195 = “3C7A8D1F6”
Conclusion
In this article, we examined why the metamask getbalance method returns a hexadecimal string instead of the decimal number and has been step by step to transform the hexadecimal value into a human readable string. By following these steps, you must be able to display the Ethereum balance on a website in a format that is easy to read to users.
Remember to always check the Metamask account settings and the initialization of the contract so that everything is correct. If you continue to experience problems, seek further help!
