A little less than 3 1/4, assuming you're using common wheat flour scooped out of the container with the measuring cup and properly leveled. Density of flour varies greatly due to its compressibility. If you sift the flour, the measurement will be way off. Your best bet is to borrow a scale.
3 cups (420 gr.) + 2 spoons (30 gr.)=450 gr. flour
Grams and grams are the same unit of measurement. Therefore, 450 grams is equal to 450 grams.
0.45 grams
There is 125 grams in a cup. So 450 is 3.6 cups
550 grams of flour is equal to approximately 1.21 pounds.
450 milligrams = 0.450 gram
When measuring flour, 409 grams would be equal to 1.73 cups. One cup of flour would be equal to 236.59 grams.
That is approximately 3.61 cups
450 grams is a unit of mass measurement equal to 0.45 kilograms or approximately 0.99 pounds.
There are 453.59237 grams in one pound. Therefore to get amount of pounds in grams, value in grams has to be divided by amount of grams in one pound: 450 grams = [grams] / 453.59237 = 450 / 453.59237 = 0.9921 pounds
That is 450 grams
There are 450 grams in a pound, so 1300 grams = 1300/450 = 2.9
