Finder on macOS uses base 10, so "GB" stands for 1000*1000*1000 Bytes. du(1) uses base 2, so "G" means 1024*1024*1024 Bytes.
It's for this reason that I've always referred to the base-10 usage as "marketing MB", because the numbers are bigger. There is a trend to use e.g. "MiB" and "GiB" for the real number (amongst us computer freaks who use base-2).
