You can use:

  du -h --time | numfmt --from=iec --to=iec --format %10f

Though more naturally you can use:

  du -B1 --time | numfmt --to=iec --format %10f

Since these are formatting for human consumption,
there are varying preferences etc, and so
(variants of) the above are appropriate for aliases,
or shell functions if accepting parameters.

There are backwards compatibility issues to consider.

cheers,
