How do I convert grams of milk to cups and ounces?


I'm having the hardest time converting grams of liquid in recipes to cups and ounces (nope, I don't have a scale -- I don't bake often enough to justify it). The liquid used most often in these recipes is milk. Isn't there a standard conversion list for milk somewhere for grams to cups or vice-versa?

To convert simply "Google" your conversion.
Here is a converter from grams to ounces.

Happy Baking!!

There are also apps for this. I have one on my iPad.

1030 grams of milk is about 1 liter = 1.06 quarts. Unless you are doing exact chemistry, I would use 250 grams = 1 cup. This will work fine if the liquid is approximately the same density as water (water, milk, cream, vinegar, etc.)

If you are measuring other liquids with a much different density, this measurement will be off. If your liquid floats (or sinks) in water, the density is different (molasses, oil, etc.) and you will need to either convert the formula based on density, or weigh your liquid.

Good luck

Cream is not the same density as milk.

A cup of whole milk weighs 244 grams, which is slightly more than a cup of water, which weighs 237 grams.

However, a cup of whipping cream weighs only 120 grams.

Some other liquids:

1 cup of honey weighs 339 grams
1 cup of molasses weighs 328 grams
1 cup of maple syrup weighs 315 grams
1 cup of corn syrup weighs 310 grams
1 cup of olive oil weighs 216 grams

This is a very simple site for Metric/Imperial Conversion....

Hope this helps you.

You can convert anything into anything using this:

I have found this so useful over the years, not just for baking.

Good morning to you. You have received enough information to start a nationwide bakery bizzznizzz. or perhaps to teach this subject at your local university.

You as a amatuer baker like we all are here & being practical all you need to know is the following.

16,oz = 454 grams.
2, TBLS of milk =1,oz.
1, cup of milk = 8,oz.

If you divide 454 grams by a constant 28.35 you will have 1, pound = 16, oz.

If you require further assistance post back it is available to you. Enjoy the rest of the day.

Mike - I had to reply to this because I think you are way off on the whipping cream. Butterfat density is I think about .875 g/cc, so a cup of pure butterfat would weigh in the range of 210 grams. Heavy whipping cream is about 40% butterfat so that will be denser, Light whipping cream is around 30% and half and half is less than 20%

I bet your source was giving you the weight of a cup of whipped cream. That would make total sense.

It is interesting that "heavy" cream is lighter per unit volume than "light" cream ;~)

Make sure that you do not compare fluid ounces with avoirdupois ounces (weight). They are close for water (1 fluid ounce of water weighs about 1.045 ounces at room temperature), but they are not exact. It is bad form to assume that an ounce is an ounce! It is not surprising that the British and French who gave us these measuring systems have converted to metric!

Now I really feel that we have shared too much :^) Webdiva you are getting much more than you paid for!

Thanks for catching the error.

I thought it seemed awfully low at the time, though I checked it twice. (I should have checked another source, but I was taking a break from a task that wasn't going well.)

It wouldn't be the first time I've gotten bad information from that site. (I've written them multiple times to correct one of them, they have the wrong weight for 1/4 cup of Nutella, it is more likely the weight of 1/2 cup.)

I'm nearly ready to give up on the Calorie Count site, you're supposed to be able to pull an ingredient by code number, but that isn't working for any of the 'heavy cream' entries in their food dictionary. (My wife is less than pleased with the new WeightWatchers site, but it seems to indicate that a cup of whipping cream is fairly close to the weight of a cup of milk.)

It doesn't always work to use the nutrition label on the side, because it appears to use a tablespoon as a single serving and the federal standard rounds everything to whole grams, eg 15.0 grams, though 15*16 = 240 so at least it's in the right ballpark.

I also found what seems like inconsistent information on Yahoo, where it says that a cup of milk weighs 8 ounces and a cup of heavy cream weighs 8.4 ounces. But if that was the case, wouldn't the cream sink to the bottom rather than float to the top?

I'm thinking of making something in the next few days that uses heavy cream, I'll have to weight out a cup and see what I get. (I still need to pick it up at the store.)

I'd go back and correct the earlier post, but this site is configured to not allow editing to a post once someone has replied directly to it. (That seems rather pointless to me for this site, though I understand why some sites mandate that.)

Good afternoon to you. Thank you for your interest in this matter. What information you stated I am certain is correct & accurate. But & however my good friend, let us be fair, let us re~read & review the original post. ALL THIS ONE PERSON WISHES IS A PRACTICAL WAY TO FULFILL HER RECIPE, EMPLOYING CUPS/TBLS & A WAY TO EXCHANGE GRAMS INTO CUPS/TBLS...I DID THAT METHOD FOR HER....WHY, SIMPLY BECAUSE SHE DOESN'T OWN A WEIGH SCALE...FURTHER SHE ISN'T A PROF BAKER.
Enjoy the rest of the day my good & learned friend.
