Calculating Grams of BCAA's

I’m taking optimum nutrition BCAA’s at the moment…

What id like to know is, how does one calculate the total grams of bcaa’s they consume daily…

Per serving:

L-Leucine 500mg
L-Isoleucine 250mg
L-Valine 250mg

Does that mean there is one 1g of BCAA per serving… ?

Yep
