How much weight of sub base will be equal to 1 cubic meter?

Answer 1

Metric mearues are easy to work out! I litre of water weighs 1kg, 1,000 litres weighs 1000kgs (i.e a metric ton). 1 cubic metre of water is 1,000 litres so it weighs a ton.

All other materials can be compared to this (i.e the 'relative' density or specific gravity). The relative density of soil is 1.8 so it weighs 1.8 times more than water for the same volume, therefore 1 cubic metre of soil weighs 1.8 tons. A solid lump of cork on the other has a relative density of 0.24 so it weighs 0.24 tons per cubic metre. One cubic metre of steel weighs 7 times more than the same volume of water so it weighs around 7 tons. Concrete, similar to solid rock comes in at around 2.5, so it weighs 2.5.

To answer the question - sub base has a relative density of loose, dry gravel is 1.9 so a cubic metre will weigh around 0.9 tons.

There are many places online that will give you a list of fifferent relative densities for materials of al sorts.

Answer 2

The weight of sub base can vary depending on the material used. However, on average, 1 cubic meter of sub base material weighs around 1.5 to 2.2 metric tons.
