Measuring 300g of Granulated White Sugar in the Kitchen

Because 1 US Customary Cup (236.6 mL) of granulated white sugar weighs 200g when measured poured or spooned & leveled, 300 Grams (300g) translates to 1.50 US cups (1 ½ cups). By contrast, using the dip scooped measure (210g/cup — a 10g per-cup shift), 300g occupies 1 ⅓ cups + 1 tbsp + 1 ½ tsp (1.43 cups).

Without a kitchen scale, measure 1 ½ cups (24 tablespoons total) using poured or spooned & leveled technique. Pour sugar directly into the measuring cup and level with a flat blade. Dry granulated sucrose crystals flow freely without trapping excessive air.

Frequently Asked Questions

How many cups is 300 grams of granulated white sugar? ▾

300 grams of granulated white sugar (poured or spooned & leveled, 200g per US cup) equals 1 ½ cups (1.50 US Customary Cups, 1.42 Metric 250 mL cups, or 24 tablespoons).

Why does granulated sugar weigh exactly 200 grams per cup? ▾

Pure sucrose crystals pack into a uniform bulk density of approximately 0.85 g/cm³, arriving reliably at 200g per US cup.

Does granulated sugar absorb moisture from the air? ▾

Yes, prolonged humidity causes surface dissolution and clumping; store in a dry, sealed airtight canister.
