Use our cups to grams weight converter to convert American cup recipes into grams in a matter of minutes. There is no need to miss out on whipping up your favourite recipes!

If you've ever tried to cook from an American recipe book, it's clear that the weights and measures used vary quite a bit from the metric measurements we use in the UK.

Wondering how many grams in a cup? Or whether a cup of flour converts to the same amount in grams as a cup of milk? These are all questions we've asked time and time again ourselves so we've decided to create this handy weight conversion tool to help you convert cups to grams in a flash.

US Cup Converter

Make sense of our US recipes by converting the cup measurements below...

Make a little more sense? Now check out our great American recipes. Traditional US recipes use cups not grams, but don't worry - you can find a version of this tool on every page where you need to make a US to UK weight conversion. Happy cooking!

It's more exact to use our tool above to convert your cups to grams, but here is a rough guide for you to print out if you'd prefer.

If you mean, would someone from the USA convert this to grams for you, then one pint is 8 ounces, which works out to approximately 340 grams, or 2 cups sliced berries.


It's approximately half of a 250g block of butter in the UK. Here's some conversions I found on another blog, where someone was kind enough to get some and do all the measurements: 1 stick of butter = 1/4 pound 1 stick of butter = 1/2 cup 1 stick of butter = 8 tablespoons 1 stick of butter = 4 ounces 1 stick of butter = 113 grams


Can someone plz tell me how much grams is 1 cup heavy cream


This would be more helpful if it went both ways (i.e. grams to cups).


1 cup of yogurt?

dipa patel

please can u discuss yogurt measurement


I have a really bad case of toenail fungus...Help!

The converter is brilliant but will someone please tell me what a "stick" of butter weighs?


I'm from America. I'm always having to convert to UK. The easiest way to convert dry measure is to use the liquid measure ml measuring cups because when I measure flour for instance, I C flour USA = 250 ml metric on my measuring cup. I cup strawberries would be 250ml. I C butter would be 250ml. Using the ml for the metric unit of measurement for American recipes will be spot on.




Please what is a stick of butter?


As someone said, you have your ways and we have ours, but sometimes we would like to try out your recipes and get stuck. It probably all goes back to the days of the pioneers and cowboys, where they didn't have scales and accuracy didn't matter all that much. A cup of this and a spoon of that, etc. People were hungry and as long as it tasted OK and was edible, then that was fine. I solved part of my problem by buying a set of cup measures the last time I was in Canada (probably the same as the US). These indicate Cups, centiliters and ounces. I also think the conversion table could be most helpful. I come from Britain but live in Switzerland, so had to get used to converting weights and measures a long time ago. Having been brought up with pounds, shillings and pence, inches, feet, yards, furlongs and miles, and much more, I found metric SO easy. But it still has to be converted.

This. Is. So. HELPFUL!!!!!!!!!!


I'm an American, and I remember being in grade school when they taught us the metric system in preparation for a conversion since "the rest of the world was using it," and then the conversion never happened. I'm in agreement with you -- I think we should have changed a long time ago! It would make life easier all the way around. I'm in the medical field, so much of what we do is often measured in the metric system (temps often recorded in C; swelling or wound sizes measured in cm,...), then we have to convert to explain to patients, and even just for things to make sense in our own minds (okay, a wound is 1 cm long and 2.5 cm = 1 inch, so how big is the wound?....) I don't necessarily agree that we are any less accurate or more awkward in msmts. because of our system (I think the CONVERSIONS can be inaccurate...), but it would just be easier if we converted to the metric system along with everyone else.


Keith - no our butter is usually 250g for standard size. We don't usually have smaller portions unless from local farms.


Don't you guys buy butter in sticks?


Sorry but we don't try to convert you, do we? We do things our way, you yours.


Why should we? Cups and lbs work better for us.


A really easy calculation guide!!!!

Hi All, what would 1/2 cup apple sauce be in grames, would assume same as glased cherries??? but was hoping someone might have a more definate number :-) thanks in advance


When using a search engine to work out cup to gram measurements it is always lower than your conversion chart, why is this? Which chart should i follow?


One pint fresh strawberries. USA convert to gramms please


HI I've found a nice vegetable broth recipe but all of the vegetable amounts are stated in cups. For eg 4 cups of winter squash, 4 cups of cabbage, 4 cups root vegetables etc. How do I find out the equivalent UK weights for these. Thanks in advance.


Hi, why is it that when I keyed in the ingredient (fr the drop down menu ) on ap flour it gives me a reading of 140 gm for a cup whereas your main table gives 150gm - which one do I follow ? Thank you, Joyce

Janet Trent

just tried it works fine and very helpful


....and maybe because there's a big wild world out there, and people from other countries like to try different things? As far as I know, I don't think anywhere in the world except US uses sticks (as is butter), cups etc... although I'm sure someone will correct me if I'm wrong!

Lee Melanie

Can someone tell me how many grams 2/3 cups of plain flour & sugar would weigh? I appreciate any help.


Liquid measures are different between U.K. Canada, and U.S. U.K. and Canada use Imperial measures and or metric. The U.S. uses Standard liquid measures. Example of differences 1 Imp gal = 160 fluid ounces and 1 Stan gal = 120 fluid ounces. 'nuf sed plamuk aka travellingchef

Anna Simoncicova

1 cup of kale? thank you


Rude knows no boundaries...!


finewine, but I don't think this method is gonna help you if you have a recipe in grams or dekagrams ... as converting e.g. sugar - granulated, powdered or brown as well as different flours is not the same ... you can't do it with this ml technique I am afraid ...


Same amount. 1ml = 1g.

Helen Miller

I have a recipe that says 200ml sugar how and 300ml flour how much in grams or cup measurement?

Jessica Hepple

Or just buy a set of cup measures and save all the faffing about with conversions. I'm a Science teacher. I work in metric at school, but still use imperial at home especially when cooking and dressmaking. I use a lot of US recipes so bought a cheap set of "cups". Ranging from an eighth upwards

Morag Hughson

I'm unsure which is correct. You list a few dried ingredients already converted,like 1 cup caster sugar, 1 cup flour, and 1 cup sultanas but then your Convertor provides different answers to what you have listed. Which is correct?


and your comment certainly quieted that didn't

Steve Branley

Whilst I agree their system is flawed in our eyes, your comments are crass and unhelpful....

Steve Branley

Because it would be kind and helpful? Just a thought....

Steve Branley

That's a very helpful comment....not. So American....:(


There are 4 sticks in 1lb (453 grams) of butter. 1 stick is therefore about 112 grams. I usually use 1/2 of a 250 gram block; seems to work fine.


All this fuss about different measurements systems. Imperial has been used for centuries, US system has grown up over two centuries and the metric since certain individuals in Bonaparte's time learned that by counting their toes as well made twenty. However, one thing remains certain. Recipes in Imperial were designed that way and work best accordingly. USA recipes are best using USA measurement systems and Metric recipes are best when that system is used. Horses for courses. Trying to mix systems or even convert is the first step to disaster.

What a hopeless site. So mant ads that the converter refuses to work! wish I could rate it as zero stars!

Bloody Americans always idiots. Why don't you use grams for everything?? Now you need to remember how much is a cup in grams for every existent food on the planet??? Thats what an heavy McDonald diet does to the brain of people.


Thank you Charlotte for your quick and easy solution to my need for a conversion of 1/2 cup of fluid to fluid ounces. Extremely useful and now bookmarked for further use :-)

Trisha Tybor

Attempting to use my great grandmother's cookbook - Radiation Cookery Book 1937- having difficulties with dry measures. Could you please tell me how many cups equal 1/2 lb of flour, 1/2lb of sugar. Also, what is the ingredient "spice" I have a US "baking spice" a combination of cinnamons, anise , allspice, mace and cardamom. Is this similar? Thankfully, I have the Mark4 down pat! Sorry to be so involved. Thank you.

Hi i have measuring cup but 1 cup is 250 ml so how to measuring all ingredients i m so confused

Hussain Areen

1/8 cup = 30g 1/4 cup = 55g 1/3 cup = 75g 1/2 cup = 115g 2/3 cup = 150g 3/4 cup = 170g 1 cup = 225g

Reluctant cook!

Brilliant! Thank you SO much - took the guess work out of converting a recipe!


I do know that Americans are pretty backward when it comes to measurements but never realised it was that bad! Now let me see: 1- Honey is a dry ingedient! 2- Even though 1 cup of liquid is 225.00ml in certain occasions it can be 240ml. 3- You have to have a set size cup to measure everything! You have signed to use the metric system almost a century ago, but no, you are so arrogant/lazy (delete as appropriate) that you decided not to use the only system that is comprehensively thought out. Instead you continue with the Inperial system that is based on the whims of your old rulers. What an irony! Almost three centuries later you are still 'ruled' by those kings and queens. You even use One's finger and foot lenght to measure distance! Loughing out Loud!
