Baking Dry Goods Density: Flour, Sugar & Salt kg to L
1 litre of flour is 0.593 kg; sugar is 0.845 kg. Master cup-to-gram conversions, bulk density, and aeration shifts with our USDA baking guide.
You are pulling a dense, brick-like loaf of sourdough or collapsed sponge cake from the oven, wondering what went wrong with your measuring cups. Dipping a cup into packed flour adds up to 30% more dry starch than a sifted scoop, throwing off hydration ratios and turning tender pastries into rubber. Here is the reality: dry powders are defined by bulk density. 1 litre of all-purpose flour weighs 0.593 kg, whereas granulated sugar weighs 0.845 kg.

1. Why Dry Baking Ingredients Are Measured by Weight
Professional bakers calculate recipes using Baker's Percentages, where every ingredient is proportional to flour mass.
Volume measurements like cups, spoons, and litres are inherently inconsistent for dry goods because powders trap variable amounts of air. Granulated sugar does not compress significantly, but wheat flour compresses dramatically when tapped or scooped.
We have all experienced uneven batches when switching measuring cups. To understand how professional kitchens bridge these volume discrepancies, explore our baker's volume to mass guide.

3. Practical Kitchen Conversion Calculations
Converting bulk ingredients between litres and kilograms uses straightforward multiplication:
Weight (kg) = Volume (L) × Bulk Density (kg/L)
Volume (L) = Weight (kg) ÷ Bulk Density (kg/L)
Everyday baking batch examples:
- 2 Litres White Sugar: 2 L × 0.845 kg/L = 1.690 kg. Test your sugar batch on our sugar calculator.
- 500 g Salt: 0.500 kg ÷ 1.220 kg/L = 0.410 L (410 ml). Explore salt in litres.
- Rice Storage Bin (10 Litres): 10 L × 0.850 kg/L = 8.50 kg. Calculate dry pantry staples with our rice calculator.

4. Frequently Asked Questions About Dry Baking Goods
How much does 1 litre of flour weigh in kg?
1 litre of spooned and levelled all-purpose flour weighs approximately 0.593 kg (593 grams). If packed tightly, it can weigh up to 0.650 kg.
How much does 1 litre of granulated sugar weigh?
1 litre of granulated white sugar weighs approximately 0.845 kg (845 grams). Sugar crystals pack more efficiently than flour, making sugar roughly 42% heavier by volume.
Why is table salt so much heavier than sugar?
Table salt (sodium chloride) has an ionic crystalline structure with a true mineral density of 2.16 kg/L. Even in granulated table salt form, its bulk density is 1.220 kg/L, compared to 0.845 kg/L for sucrose sugar.
How many litres is 1 kg of flour?
1 kg of all-purpose flour equals approximately 1.686 litres (1,686 ml). Dividing 1 kg by 0.593 kg/L gives 1.686 litres.
Can I substitute powdered sugar for granulated sugar 1:1 by volume?
No. Powdered confectioners sugar has a bulk density of 0.510 kg/L, while granulated sugar is 0.845 kg/L. 1 cup of powdered sugar weighs only 120 grams versus 200 grams for granulated sugar.
