Yeah, I can’t do that.  Math was never my strong subject. 

Thankfully, I don’t have to convert anything in my head anymore — here’s a great conversion tool that you should bookmark.

Also, if you’re like me and buy your yeast in a jar (though I’m starting to reconsider since it does lose some “rising” qualities the older the jar gets…even when it’s only a couple of weeks old).  Anyway, when recipes call for 1 packet of yeast, that’s 2 1/4 tsp. 

Happy cooking/baking!
