System Monitor v4.0.2 beta

Hello,

I try the new system monitor and I have some questions:

How can I use TEMP in Celsius not Farenheit?

How can I use Units (Percent) in (for example) CPU_FREE?

How can I use own text, for example "Used Memory = " PHYS_USED?

I want more at the same skin. This is my skin for Memory in Gigabyte. How can I use in the same skin memory in Gigabyte AND percent? This is my xml-file:
