GRAM conversions?

  • a

I'm trying to make my own Thai style curry. I bought some real Thai curry paste, and want to try the recipe on the box. The recipe calls for "100 grams of paste" etc and I'm not sure how to convert it to tablespoons, etc. I know grams are weight units, and tablespoons etc are volumes, but there should be an easy conversion. I doubt Thai cooks and homemakes have gram scales in their kitchens. Can anybody clue me in? Thanks.

      WOW, that's terific! Exactly what I need. Bookmark that site, everyone, we're all gonna ned that eventually.

        Another excellent resource is good ol' Google. You can do a search for, say, 100 grams in ounces, and it will automagically tell you how many ounces that is (in this case, about 3.5). If you're working with liquidy ingredients, you can then feed the result back into Google but this time as ounces in cups (.4375 c, roughly 1/2 cup minus a tablespoon). Or if you're mathematically inclined, remember that a fluid ounce is 2 tablespoons.


    2. There is no easy way to convert it since the density of each product is different. density = M/V. Without knowing the density you can use the normal converter pages which will give you only an approximate number. There is a reason why IUPAC decided to use g and mL as the standard for weight and volume throughout the world and I think every cookbook should adapt this and shouldn't use tablespoons etc.

        Yabbut... my point still applies. Are we supposed to buy gram scales for our kitchens? I've used gram scales for years in schools and laboratories, yet it would be had for me to guesstimate how much curry paste "100 grams" would be. And I kinda doubt gram scales will become common in home kitchens, particularly in third-world countries like Thailand.

          All the German houses I was in (of friends that cooked)had scales out on the counter - I have one but it's in the back of a cabinet - use it once in a while. All German cookbooks use grams (ones I saw). Using weight (or mass if you have a balance) is supposedly more accurate, esp for dry measures, eg- flour, where packing density becomes moot.

          1. re: Andrew Gore

            The point is to do things by weight, not volume. 100 grams is 100 grams; volumetric measurements can vary in density.

        2. How many grams are in the package of paste? Can't you deduce the amount based on the volume?

          1. Great gram conversion site, thanks Pat.

            But still--if the package you have is 450 grams and you need 100 grams, a pinch over a quarter of the package will do it, no? Density or no density...
