Soil Weight per Cubic Metre (kg & Tonnes)
Using LandscapeCalc's topsoil planning coefficient, one cubic metre (1m³) displays as 1,100kg, or 1.1 tonnes. Select a soil type below and confirm the result with its supplier.

Total Volume
What the Soil Weight Result Means
The page starts with a 1m × 1m area at 1,000mm depth, which is exactly one cubic metre. With topsoil selected, LandscapeCalc multiplies that volume by its 1.10 tonnes-per-cubic-metre planning coefficient to display 1.10 tonnes, or 1,100 kilograms.
It Is a Planning Coefficient, Not a Product Specification
Soil density changes with composition, screening, organic content, moisture and compaction. For comparison, Australian Native Landscapes publishes indicative loose values of 1.4 tonnes per cubic metre for topsoil and 1.2 for garden mix, while warning that actual products vary. LandscapeCalc's complete coefficient list and source policy are documented on the Methodology & Sources page.
How to Use the Estimate
Order bulk soil primarily from the calculated cubic metres. Use the weight only for an early delivery discussion, then replace it with the selected supplier's current conversion. Do not use this estimate to decide whether a vehicle or trailer can legally or safely carry the load.
For a different area or depth, use the main soil calculator and enter the dimensions from your project requirements.
