[Suggestion] "Human readable" output

[Atemu]

Give us the option to display the speed in "Human readable" format from coreutils du

‘--human-readable’ Append a size letter to each size, such as ‘M’ for mebibytes. Powers of 1024 are used, not 1000; ‘M’ stands for 1,048,576 bytes. This option is equivalent to --block-size=human-readable. Use the --si option if you prefer powers of 1000.

40000kbps becomes 40Mbps, 0.1kbps becomes 100bit/s, 1000000KB/s becomes 1GB/s etc.
