can grams/cylinder be converted to KPA in efi live

I cut my teeth on OBD1 using Tunerpro RT and EVERYTHING to do with vacuum was in KPA. I don't know what this grams/cylinder stuff is on the spark and Map psi on the VE table but is there a way to make EFI live display anything vacuum related in KPA?

But can I somehow change the formula so it shows KPA on all vacuum based tables in EFI live? .044 grams/cylinder doesn't mean jack to me. KPA is so much easier to understand.

The spark tables use the g/cyl instead of kpa. Every ls platform I've seen does. The tables are what they are, I prefer the g/cyl because in any given log 98 kpa may be .44 or .88 g/cyl depending on how much air your setup will pump.
