How to change the output unit notation when using the number_to_human_size ActionView::Helper

Question

I have been using the excellent number_to_human_size ActionView::Helper and I was wondering if there is any way to change the output unit notation:

The default behavior is to output the units in Bytes, KB, MB, etc while I would like to see Bit, Kb, Mb etc.

The number conversion is correct, I only want to change the unit name. I have figured out that using locales could be a solution and have added this in my en.yml:

en:
  storage_units:
    format: "%n %u"
    units:
      byte:
        one: "b/s"
        other: "b/s"
      kb: "Kb/s"
      mb: "Mb/s"
      gb: "Gb/s"
      tb: "Tb/s"

...but doesn't seem to work.

Has anybody ever dealt with this challenge?

Thanks in advance,

Petros

With Rails' number_to_human_size you can just do a gsub to replace values in the suffix.

number_to_human_size(1234567890).gsub(/(Bytes?|B$)/,'b/s')
# => "1.15 Gb/s"
