How it is calculated
grams = amount × unit size in US cups × 120. 1 tbsp = 1/16 cup, 1 tsp = 1/48 cup, metric cup 250 mL = 1.0567 US cups. 1 oz = 28.3495 g.
Example
Inputs: Amount = 0.5, Unit = US cup (236.6 mL). Result: Weight in grams: 60 g; Weight in ounces: 2.12 oz.
Limits and caveats
- The weight assumes spoon and level; dipping the cup into the bag packs the flour and weighs more.
- Chart figures are rounded to the gram, and a scale is more exact than any cup.
- Metric cup (250 mL) and spoon values are scaled by volume from the 236.59 mL US cup figure.
Questions about this tool
How many grams is 1/2 cup of bread flour?
Half a US cup is 60 g, because a full cup is 120 g in the chart; a quarter cup is 30 g.
Is bread flour heavier than all-purpose flour?
The King Arthur chart gives both 120 g per cup. The difference is protein content, not weight per cup.
Why do cup weights differ between websites?
Charts assume different ways of filling the cup. This tool uses the King Arthur Baking ingredient weight chart: 1 cup of bread flour = 120 g, spooned into the cup and leveled.
