Hydrogen Peroxide (30%) weighs 1.11 kg per litre. Convert litres to kilograms (and back) using its exact density.
Quick Metrology Summary
1 liter of Hydrogen Peroxide (30%) weighs approximately 1.11 kilograms (or 1110 grams) at standard room temperature. Because mass equals volume multiplied by density (\(m = V \times \rho\)), multiplying volume in liters by 1.11 gives the exact mass in kg.
Hydrogen Peroxide (30%): Weight per Litre Explained
Hydrogen Peroxide (30%) has a density of 1.11 kg/L, which makes it 11% heavier than water. Commercial 30% hydrogen peroxide is a water solution with a density of about 1.11 kg/L, roughly 11% heavier than water.
When You Need This Conversion
Bleaching, disinfection, rocket-propellant research and water treatment. Concentrated peroxide is an oxidiser that needs careful handling.
What Changes the Density
Concentration is the whole story: 3% pharmacy peroxide is about 1.01 kg/L, 30% is ~1.11, 50% is ~1.20, 90% is ~1.39 and pure H₂O₂ is ~1.45. Always confirm your grade.

How to Convert Liters of Hydrogen Peroxide (30%) to Kilograms
Commercial 30% hydrogen peroxide is a water solution with a density of about 1.11 kg/L, roughly 11% heavier than water. To convert, multiply the volume in litres by 1.11. To go the other way, divide the weight in kilograms by 1.11.
kg = Litres × 1.11
L = kg ÷ 1.11
1 L → 1.11 kg
10 L → 11.1 kg
100 L → 111 kgExample
Convert 5 litres of hydrogen peroxide (30%) to kilograms: 5 × 1.11 = 5.55 kg, or 12.24 lb. Reversed: 5.55 kg ÷ 1.11 = 5 L.
Worked examples
| Scenario | Calculation | Result |
|---|---|---|
| 1 L of hydrogen peroxide (30%) | 1 × 1.11 kg/L | 1.11 kg |
| 5 L of hydrogen peroxide (30%) | 5 × 1.11 kg/L | 5.55 kg |
| 20 L of hydrogen peroxide (30%) | 20 × 1.11 kg/L | 22.2 kg |
| 100 L of hydrogen peroxide (30%) | 100 × 1.11 kg/L | 111 kg |
| 10 kg of hydrogen peroxide (30%) (reverse) | 10 ÷ 1.11 kg/L | 9.01 L |
