How it’s calculated
1 US cup of granulated sugar ≈ 198 g · 1 tbsp ≈ 12.375 g · 1 metric cup (250 mL) ≈ 209.22 g · 1 UK cup (284 mL) ≈ 237.79 g
grams = US cups × 198
Step by step
- Multiply by the weight of one cup: 1 × 198 g = 198 g.
Granulated sugar pours evenly, so cup measures are fairly consistent; fill and level the cup. Weighing is more accurate than cups; weights vary with how the cup is packed.
