conversion grams to cups??

Ok, so lets break this down..
First How many grams in an ounce?
1 ounce = 28.34 grams SO 28.0 grams = 1oz
Second, we know that there are 8oz in one cup.
lets multiply 28.0 grams by 8 (because we know that 28.0 grams = 1oz and 8oz is equilant to 1 cup)
28.0 x 8 = 224g in one cup
So, 1/2 cup is equal to 112grams.
Sincerley,
Phaty
Hope that makes senseLast edited by ctgblue; 12-28-2005 at 12:05 PM.

Thanks phaty!!!
that makes a lot of sence!
the reason why I ask, is because a sports nutritionist altered my diet, and suggested 2.5 cups of veggies. I thought that it would be easier just to weigh the veggies!
so 2.5Cups = 560gms :-)
Thanks again, cya

umm... grams is a weight measure. You can convert between grams and ounces but not between grams and FLUID ounces which is a volume measure. So it is different for each food.
There are 8 FLUID ounces in a cup. A cup is a volume measure.
A gram is a weight measure.
It depends on the fluid/food density!
ie. Density = Mass/volume SOOO... mass = volume * density ...
Legal Measurement conversions:

Bump Terracotta.
You can't convert between unlike measurements, i.e., weight to volume.

If you want to convert cups to ounces, here's what I did when I wanted to get "technical."
Go to the USDA database website... http://www.nal.usda.gov/fnic/foodcomp/search/
Look up the food you want. Choose a 1 cup serving. Then check out how much 1 cup of that vegetable weighs in grams. Divide that number by 28 grams, and you will get the weight, in ounces, of how much 1 cup of that particular vegetable weighs.
For example:
1 cup of Raw Broccoli weighs 91 grams.
91 divided by 28 grams equals 3.25 oz
So... 1 cup of Raw Broccoli weighs 3.5 oz
1 cup of Raw Spinach weighs 30 grams
30 divided by 28 grams equals 1.07 oz
So... 1 cup of Raw Spinach weighs 1.07 oz
1 cup of Chopped Tomatoes weighs 180 grams.
180 divided by 28 grams equals 6.42 oz
So... 1 cup of Chopped Tomatoes weighs 6.42 oz
I made a chart of all my favorite fruits & veggies a while back... including weights in ounces, and "net" carb values... but I lost my hard drive.www.AOL scanner.com

thankyou soo much dragon princess and Ms Highside for posting those web sites.
I just spent a couple of hours working out the cals etc in the veggies/salads I eat.
The total cals etc when combined work out differently compared to the general "vegetables NS" category posted on fitday, but I thinking working out each vegetable individually is more accurate :-)
Thanks again, im sure I will be using the USDA web site regularly!!

Using my example above, it's easy to see that different foods weigh differently for the same "cup" serving. Somebody actually filled a "cup" and weighed it... for each of the veggies listed on their website. Talk about annoying work. LOLwww.AOL scanner.com

yes, I agree with you Ms Highside (ie time consuming!). Originally, I thought that there was a simple way you could work out 'two cups = so many grams'. But after your post and the web site, it seems so obvious that each vegetable etc is different!
...and yes, it is very time consuming writing down each food, but once you've entered it in to fit day, that will automatically change the ratios/cals etc according to how much of that veggie you plan to eat...ALOT more accurate!
anyway, thanks again :-)

I had to do that with alot of veggies on fitday. I could never figure out what a "stalk" of broccoli was. Nor a "cup" of lettuce. I've got hundreds of custom foods in my account.
Atleast I won't have to enter them again.www.AOL scanner.com
