1 gwei = 0.000000001 ether

There's a program that displays only 156489673002 (156 gwei), which is 0.000000156489673002 ether.

But how to, in Bash, calculate how many ether is 156489673002 (so the output is 0.000000156489673002)?

    You use, instead of bash, a language which can do fractional arithmetic: `bc`, `awk` and `zsh` for instance, though if you need high precision, `bc` is probably the best choice. Other good alternatives are i.e. Ruby, Perl, Python and others. – user1934428 Nov 29 '21 at 08:11

You can get the result with awk:

echo "0.1 0.1" | awk '{printf "%.18f\n", 156489673002 / 1000000000000000000}'

or

echo "0.1 0.1" | awk '{printf "%.18f\n", 156489673002 / 1e18}'
