Read a .txt file using batch and extract a string between ()

Question

I have a .LOG file whitch contains:

2015-01-20 17:00:59 (15.6 MB/s) - `c:/temp/teste_velocidade.tar.gz' saved [253311/253311]

I'd like to extract the content between "(" ")" into a variable.

Ex.:

$number=15.6
$unit=MB

How can I do This?

I'm seaching for a solution for it but batch is not familiar to me.

Like this :

@echo off

for /f "tokens=3,4 Delims=() " %%a in (test.log) do (
  set "$Number=%%a" 
  set "$Unit=%%b"
)

echo Number : [%$Number%]
echo Unit   : [%$Unit%]

I Used here a file named test.log for the test
