# 330g of caster sugar = how many US Cups?

Is anybody good at converting grams (caster sugar) to US cups? From the conversion charts I have found I am thinking 1-1/4 cups (but not sure about the 1/4). Anybody a genius at this? Because I am not :) Thank You!

Seriously, thanks all! OCD brain has kicked into high gear :) I'll use superfine sugar and go for 1-2/3 C, which is slightly under 1-3/4 and that matches close to Regine's figures. Everything should be perfect, now. Well, after this sneezing and coughing has left my body...

I'll add my 2 cents. Caster sugar is slightly heavier per cup than regular US granulated sugar. I come up with 225 grams per cup, so 330 grams is 1.47 cups (1.5 cups minus 1.5 t.) If you're using regular granulated sugar it's 200 grams per cup, so you'd want to use 1.65 cups (which is close enough to 1 2/3 cups for me, but you could subtract a teaspoon and it would be close to perfect.)

Lapadia, I found a conversion chart (http://www.traditionaloven.com/conversions_of_measures/sugar_amounts.html). 330 g = 1.47 US cups.
I think some of the fuzziness here is due to the nature of caster sugar, which is like American superfine sugar, so it may pack down more for the same weight.

I will go with Regine's figures...thanks again!

It s not 1 1/2 cup but 1 3/4 cup minus 1 1/2 tsp

Oh how perfect, Regine, I LOVE it! Math genius :)

I get just less than 1 3/4 cups. According to The Cake Bible, 1 cup is 200 grams.
Here's my math: 200 g=1 cup
+100 g=1/2 cup
+30 g=2 tablespoons+1 teaspoon
= somewhere right between 1 1/2 and 1 3/4
