Grams to Cups & Ounces to Cups. I googled and did the math, but still feel a bit insecure. The pie crust recipe I'd like to use is in grams and ounces and alas I do not have a scale. Does 315 grams flour = 2.5 cups read right? 5.5 ounces butter = 11 Tablespoons & 3 ounces shortening equals 0.8 cups? I figure I'd start with less than I think I need and add until the desired dough consistency... but help would be nice. Thanks!

The brand of flour and your region can play a factor. Gold Medal AP is 130g/c, USDA AP flour is 125g/cup..while king authar claims all it's flour is 115 g/c. (doubtful).

The shortening issue points to one of the problems in conversion. American measures use ounces for both weight and fluid (volume) measure, so an ounce can be 1/16th of a pound or 1/8th of a cup, and they're not always the same thing. Metric measurements are more specific.

Hello A:
It would be so much easier to just get yourself a scale. I got a digital scale at W*lmart for about 15 dollars and it will weigh ounces/lbs as well as grams/kilos. Weighing will be simpler than calculating.

Thanks! These were the answers I needed! Sfmiller - thanks for correcting my shortening calculations. I thought my original estimate seemed like a lot!

The conversions for the flour and butter are OK, but the one for shortening is incorrect.

3 oz shortening = 6 Tbsp = 3/8 cup ( or .375 cup), not 8/10 cup.

As corrected, the fat to flour ratio seems about right for the recipe to work. 8 oz total fat to 2.5 cups flour is standard ratio in pie crusts; you'd have 8.5/2.5.

The conversion will be a bit dodgy, this is why it is better to weigh everything, but I am sure you do not have a pastry scale, otherwise you would not be asking. I know there is 28.3495 grams per ounce.

Just try it and see, you may have to make a couple of batches to get it right. In the end you will learn what doesn't work
