What 450 grams looks like

450 grams is 15.8733 ounces by weight (0.9921 lb), whatever the ingredient. The cups depend on what you are weighing. 450 g of whole wheat flour is very close to 4 cups; 450 g of powdered sugar is very close to 4 cups; 450 g of butter is very close to 2 cups; 450 g of dry rolled oats is very close to 5 cups.

At this size a scale is faster than cups: 450 g of flour is 3 ¾ cups spooned and levelled, and the difference between a light and a packed cup adds up to a full cup's error over a bag-sized batch.

450 grams in metric cups and ounces

In a 250 ml metric or Australian cup, 450 g of all-purpose flour is about 3.55 cups instead of 3.75 US cups, because the cup is bigger while the weight per cup stays on the same reference. By weight, 450 g is 15.8733 oz for any ingredient.

The calculation is always grams ÷ grams per cup: 450 ÷ 120 = 3.75 US cups for flour, 450 ÷ 236.5882 = 1.902 for water. Keep the unrounded figure while you work and round only what you write down.
