user138274: can someone tell me how bitcoin hash a btc address?
when you try to hash it on this website, you will get the same result as down below
Bitcoin Address : 1JKRgG4F7k1b7PbAhQ7heEuV5aTJDpK9TS
Result (Hash 160) : bdf63990d6dc33d705b756e13dd135466c06b3b5

but when i convert the address to ripemd160,  i got a completely different result
3da397753d32cea0858334e36fc58ae53f8c2529

so how do i get the same result as the first one?

user138899: To get the same result you must decode the address, which means convert the base58 to hexadecimal.
1JKRgG4F7k1b7PbAhQ7heEuV5aTJDpK9TS becomes 00bdf63990d6dc33d705b756e13dd135466c06b3b55850d39d
Where:

00 -> mainnet
bdf63990d6dc33d705b756e13dd135466c06b3b5 -> hash160 of
public key
5850d39d -> checksum
