What the "g" stand for? - when centrifuging something (Oct/12/2006 )

When something says "centrifuge at 10,000xg what does the "g" stand for? I know it's a unit but for what? I googled it and found info that said it's acceleration due to gravity and also stuff that said RCF=10,000xg, so is it relative centrifugal force? I'm trying to compile the abbreviations page for my thesis. Help please.

g is acceleration caused by gravity. It is a constant - 9.8m/s2

g is gravity, RCF is relative centrifugal force. RCF is an expression of how many g you are using to spin down your sample.

That was very useful, thanks, I also was wondering about that =)
