i am breaking my head over this, what does this number mean in ping. it was not shown in ros6.
what the “us” value mean in the end of each line. example 15ms513us . what is 513us ?

Since RouterOS & other network OS do not support characters out of ASCII-7-bit range,
usually the “µ” micro (is for small M on greek, “mi”) sign is replaced with “u” by resemblance.

This also happen on some other abbreviations like uFL for µFL connector, but on this case the correct name is U.FL

Since RouterOS also do not support floating point numbers, 15513µs are represented with 15ms513us
On WinBox are represented 15.513 (ms) because WinBox is executed on Windows/Wine) and have support for floating point numbers,
and the conversion happen inside WinBox when retrieve the value.
