Can anyone help- what are the exact formulas for finding out the g of carbs in fruit and bread if there is no label. I weight them and I can’t remember the formulas. Can anyone help???

after watching this video, I bought the Eatsmart Scale. It figures it all out for you, whether it is an apple, or part of a packaged food

There’s no formula. I love my EatSmart scale. Best money I’ve spent. It won’t help with things like bread, but it gives carbs & other nutritional info on 999 programmed foods–fruits, veggies, dairy products, oils, nuts, seeds, animal protein.
