Help, heliocentric gravitational constant

[ArthurCVI]

What is the "heliocentric gravitational constant"?

http://en.wikipedia.org/wiki/Standard_gravitational_parameter

"The value for the Sun is called the heliocentric gravitational constant or geopotential of the sun and equals 1.32712440018×1020 m3s−2."

I don't know what this equals for kerbol, but I guess that would be the keocentric gravitational constant.

Kerbol's gravitational parameter is 1.1723328×10¹⁸ m³/s². You can find this value for any body in KSP wiki.
