Garden Topsoil weighs 1.2 kg per litre. Convert litres to kilograms (and back) using its exact density.
Quick Metrology Summary
1 liter of Garden Topsoil weighs approximately 1.2 kilograms (or 1200 grams) at standard room temperature. Because mass equals volume multiplied by density (\(m = V \times \rho\)), multiplying volume in liters by 1.2 gives the exact mass in kg.
Garden Topsoil: Weight per Litre Explained
Garden Topsoil has a density of 1.2 kg/L, which makes it 20% heavier than water. Moist garden topsoil is about 1.2 kg/L. It is lighter than sand or clay because it contains organic matter and air spaces.
When You Need This Conversion
Raised-bed filling, lawn top-dressing, planter weight for balconies and roof gardens, and bulk soil deliveries.
What Changes the Density
Wet clay soils are much heavier (1.6+), while compost-rich mixes drop to 0.8–1.0 kg/L. Roof-garden designs use saturated weights.

How to Convert Liters of Garden Topsoil to Kilograms
Moist garden topsoil is about 1.2 kg/L. It is lighter than sand or clay because it contains organic matter and air spaces. To convert, multiply the volume in litres by 1.2. To go the other way, divide the weight in kilograms by 1.2.
kg = Litres × 1.2
L = kg ÷ 1.2
1 L → 1.2 kg
10 L → 12 kg
100 L → 120 kgExample
Convert 5 litres of garden topsoil to kilograms: 5 × 1.2 = 6 kg, or 13.23 lb. Reversed: 6 kg ÷ 1.2 = 5 L.
Worked examples
| Scenario | Calculation | Result |
|---|---|---|
| 1 L of garden topsoil | 1 × 1.2 kg/L | 1.2 kg |
| 5 L of garden topsoil | 5 × 1.2 kg/L | 6 kg |
| 20 L of garden topsoil | 20 × 1.2 kg/L | 24 kg |
| 100 L of garden topsoil | 100 × 1.2 kg/L | 120 kg |
| 10 kg of garden topsoil (reverse) | 10 ÷ 1.2 kg/L | 8.33 L |
