Maths can't work this out

Hi. I have found some bread I like but can't work out how mant carbs in one slice I'm soooo bad at maths. It says 58.8g in 100g. I make it in my bread maker so cutting the thinnest slice I can. It works out about 45g per slice in weight. How many carbs in one slice? Thank you.
 
Your slice has 26.46g of carbs.

58.8/100 x 45= 26.46
 
Wait a mo. Its 58.8g per 100g of product, if you make it in your bread maker and have to add liquid, then the finished loaf will weigh more than the dry weight of the product. If you use 400g of dry mix then the whole loaf will be 58.8g x 4 = 235.2g. Cut your loaf into fairly even slices, thick or thin makes no difference as long as they are all roughly the same, count the number of slices, then divide 235g by the number of slices and that will give you the carb approx of each slice.
 
My brain can't handle all of these numbers!
I hate foods that tell you in 100g, who eats 100g of most things anyway!

It's simple, just divide the amount of carbs in 100grams by 100 to get the carbs per gram, then multiply by the number of grams you are eating.
 
I only posted that because I made a loaf the other day and needed the carb content of a slice. So, duly weighed the slice, then counted the number of slices I had from that loaf and realised that the total weight of the loaf was considerably more than the 400g of product that I started off with. So its important to weigh the finished loaf. 400g of product does not necessarily reflect the total weight of the loaf because other stuff had been added. So, 400g of product gives total carbs of 235g, that 235g of carbs is spread over all the slices in your new loaf. So count your slices and divide 235g carbs by the number of slices. So if you got 15 slices from your loaf, divide 235g by 15 which equals 15,68g per slice. Sorry if it all sounds complicated, its not really.

I'm terrible at maths because I have dyscalculia, but this is the way I'd work it out. Very simple! With a calculator of course, for my broken mind.
 
It will say on the packaging if it's dried or baked weight for the carbs lilliepop.

It says? What says? It depends on where you are getting this 58.8 g per 100g from.


White flour is very high in carbs, say 75g per 100g flour.

A bread ready mix is high but generally not as high, say 45g per 100 g of finished product.

Assuming the bread mix above:

A thin slice of bread crust cut off might be 9g weight ie 4.4. g carbs

With crust, it might be 20 g weight, ie 10g carbs

A large slice might be 30g weight, ie 15 g carbs.

So your 45 gram slice could be (for example) 30g of product and 15g of water - obviously I don't know the exact amounts ;) You'd need to weigh the finished loaf.

No because when you cook it you will drive off water. Just go with the side of the packet. I would just do 60% in my head 45g is approx 22+5=27g (ie 1/2 + 1/10) rounding up and down

Bread would be pretty dry without any water in it. Some might be driven off in baking, but it's not rock hard.

Yes, 37.5% water is a reasonable average for baked white bread.

Water is the medium which transports the heat throughout the dough in the baking process.
 
I will never look at a loaf of bread in the same way again...l don't eat it now, one slice would lead to to many but EISH! lot of water less water carbs/slice size/water
