Total Download Size in pacman and pamac are different.

[papajoke]

MB and MiB are different
MB = 1000
MiB = 1024 (standard value before year 2000 BUT old notation before 2000 was MB !!!)

default format is different for all aps

free --si
               total        used        free      shared  buff/cache   available
Mem:            6083        1622        1697         130        2762        4026

free 
               total        used        free      shared  buff/cache   available
Mem:            5801        1548        1618         124        2634        3839

same result for total … but not same format

$ ls -l -h /var/cache/pacman/pkg/linux510-5.10.70-1-x86_64.pkg.tar.zst

He’s talking about that pamac or pacman displays misleading info in package update summary (#1119) · Issues · Applications / pamac · GitLab

the wording is different and may be improved.

the Net Upgrade Size in Pacman corresponds to the Total installed size in Pamac
