Issue … I stole a filter from @EricShulman and edited it to this …
<$let tids="[prefix[$:/RandomDog/]]"
count={{{ [subfilter<tids>count[]] }}}
bytes={{{ [subfilter<tids>] :map[{!!text}length[]] +[sum[]] }}}
>
<<bytes>> bytes in <<count>> tiddlers
</$let>
It is to monitor import size of Random Dogs (see: Has anyone used the Random Dog Method? - #8 by TiddlyTitch).
Q: HOW do I change the filter to give Megabytes rather than Bytes?
Best, TT
Some people define a megabyte (Mb) as 1000 Kb, where a Kb (kilobyte) is 1024 bytes
1Mb = 1000Kb which is 1024x1000 = 1024000 bytes
However, other people say that the proper calculation is
1Mb = 1024Kb which is 1024x1024 =1048576 bytes
If you use this second number, the filter math calculation is:
Mbytes={{{ [subfilter<tids>] :map[{!!text}length[]] +[sum[]divide[1048576]] }}}
-e
an abomination, but one with historical precedent (1.44 meg floppies)
In practice, the modern standards should be at least referenced here for those unaware - that megabyte (MB) is 1000^2 = 1000000 whilst 1024^2 = 1048576 is a mebibyte (MiB) (a kilobyte (kB) is 1000 and 1024 byes is a kibibyte (KiB)
Fight of the century
How many Bits in A Megabyte?
Part #7: @EricShulman v. @nemo
[[Video unavailable in your country]]
I don’t care. 24kb is nothing now.
All I need, for the purpose, is an approximation that on Mb’s there are too many.
I will test & report back.

@EricShulman, It works very well.
Can you help me round it up to two points?
I get …
6.414379119873047 megabytes in 2 tiddlers
All I need is …
6.41 megabytes in 2 tiddlers
This should do the trick:
Mbytes={{{ [subfilter<tids>] :map[{!!text}length[]] +[sum[]divide[1048576]fixed[2]] }}}

I added that at the end. All is good.
