Sodium Hydroxide Solution (50%) weighs 1.525 kg per litre. Convert litres to kilograms (and back) using its exact density.
Quick Metrology Summary
1 liter of Sodium Hydroxide Solution (50%) weighs approximately 1.525 kilograms (or 1525 grams) at standard room temperature. Because mass equals volume multiplied by density (\(m = V \times \rho\)), multiplying volume in liters by 1.525 gives the exact mass in kg.
Sodium Hydroxide Solution (50%): Weight per Litre Explained
Sodium Hydroxide Solution (50%) has a density of 1.525 kg/L, which makes it 52% heavier than water. A 50% caustic soda solution is strongly alkaline and weighs about 1.525 kg/L. It is more than 50% heavier than water.
When You Need This Conversion
Soap manufacture, drain cleaners, paper pulping, aluminium processing and neutralising acids.
What Changes the Density
Density rises steadily with strength: 10% is ~1.11, 25% is ~1.28 and 50% is ~1.52 kg/L. The solution is hot and dangerous to handle when diluted.

How to Convert Liters of Sodium Hydroxide Solution (50%) to Kilograms
A 50% caustic soda solution is strongly alkaline and weighs about 1.525 kg/L. It is more than 50% heavier than water. To convert, multiply the volume in litres by 1.525. To go the other way, divide the weight in kilograms by 1.525.
kg = Litres × 1.525
L = kg ÷ 1.525
1 L → 1.525 kg
10 L → 15.25 kg
100 L → 152.5 kgExample
Convert 5 litres of sodium hydroxide solution (50%) to kilograms: 5 × 1.525 = 7.625 kg, or 16.81 lb. Reversed: 7.625 kg ÷ 1.525 = 5 L.
Worked examples
| Scenario | Calculation | Result |
|---|---|---|
| 1 L of sodium hydroxide solution (50%) | 1 × 1.525 kg/L | 1.525 kg |
| 5 L of sodium hydroxide solution (50%) | 5 × 1.525 kg/L | 7.625 kg |
| 20 L of sodium hydroxide solution (50%) | 20 × 1.525 kg/L | 30.5 kg |
| 100 L of sodium hydroxide solution (50%) | 100 × 1.525 kg/L | 152.5 kg |
| 10 kg of sodium hydroxide solution (50%) (reverse) | 10 ÷ 1.525 kg/L | 6.56 L |
