Reporting usage in decimal instead of binary units

[berhane]

Hi,
I see duc reports disk usage stats in binary (2^x = KiB, MiB, GIB, ... etc) units by default. Can it report numbers in decimal (10^y = KB, MB, GB, ... etc) units? Other utilities have an --si flag to report numbers in decimal units, but I didn't see something equivalent with duc. If that feature is not available, it would be great to have.
Thanks.
