Borax as ph meter calibration fluid question

How much borax per cup of water to make a calibration fluid of 9.2? Randy mentions a link in this article: http://reefkeeping.com/issues/2005-02/rhf/index.php#7 but the link is dead. Thanks in advance

That one's dead too.

I'm still looking though.

It is 3.80 grams per Liter. This is 9.18 at 25 deg C. So do the conversion from Liters to cups.
