Dear maintener,

I found a reproducible bug in df utility, installed in debian stable

$ df --version |head -1
df (GNU coreutils) 8.30
$ cat /etc/debian_version
10.8

df displays G instead of GM as unit size for Gigabytes in power of 1000 
(but the value is correct)

$ df -BGB /home
Sys. de fichiers blocs de 1GB Utilisé Disponible Uti% Monté sur
/dev/mapper/ssd2        421GB   355GB       45GB  89% /home

$ df -H /home

/dev/mapper/ssd2   421G    355G   45G  89% /home

As a remark, the display is ok (no bug) with TeraBytes, MegaBytes and 
KiloBytes in power of 1000
