How many cubic meter in a tonne of gravel | how many m3 are in a tonne of gravel | yields of 1 ton of gravel.

Gravel or coarse aggregate is one of the most important building material required in every civil construction work, its required for fill the excavation area, used as backfills, required for preparing the concrete mix, it will be in round or oval, angular, pea size shaped gravel.

Generally gravel quantity measured in volume and their mass, volume of gravel based on Imperial or US customary measurement system measured in cubic yard, cubic meter, cubic feet and cubic inch. Mass of gravel generally measured in kilograms, pounds and tons.

One tonne, or metric ton of gravel weighs about 1000 kg. A cubic meter of gravel weighs about 1,680 kg. So, yields of 1 tonne gravel in m3 = 0.595 cubic meter.

Gravel is made of rock is to build roads, path, driveway, Patio, pedestrian, pavement, pathways, roadways, landscaping, and etc.

Gravel is categorised according to their size, size more than 5mm put in the category of gravel, it is formed of igneous rocks. It is categorised as fine gravel (4 – 8 mm), medium gravel (8 – 16 mm), coarse gravel (16 – 32 mm), pebbles (32 – 64 mm), cobbles (64 – 256 mm) and Boulder more than 256mm.

Weight of gravel and stone depends on the rocks type, loose and dense condition, compact, moisture content, dry and wet condition. Typical gravel density (dry) is between 1520 and 1680 kg/m3 (95 to 105 lbs/ft3). If it is mixed with sand the density is around 1920 kg/m3 or 120 lbs/ft3.

A cubic meter of typical gravel weighs 1,680 kilograms 1.68 tonnes. A square meter of gravel with a depth of 5 cm weighs about 84 kg or 0.084 tonnes. On average, a cubic meter of gravel, which visually is 1 meter long by 1 meter wide by 1 meter tall, can weigh approximately 1680 kg or 1.68 tonnes or mt.

**How many cubic meter in a tonne of gravel**

Weight of aggregate in kilogram depends on density of aggregate and size of aggregate. Lesser dimension of aggregate have high density due to less presence of air voids & higher dimension of aggregate have lower density.

A cubic meter of typical gravel weighs range between 1,400 kg to 1,680 kg, which is equivalent to 1.4 to 1.68 tonnes. 1m3 of 20mm size of gravel weighs about 1,550 kg. 1m3 of 40mm size of gravel weighs about 1,450 kg. 1m3 of 10mm size of gravel weighs about 1,680 kg. 1m3 of pebbles weighs about 1,400kg.

One tonne (1000kg) of gravel yields volume range between 0.6m3 to 0.7m3. One tonne of 10mm size of gravel yields about 0.60m3, 20mm yields about 0.65m3, 40mm yields about 0.69m3, and pebbles yields about 0.70m3.

To calculate yields of 1 tonne in cubic meter, divide weight of a tonnage of gravel (1000kg) by density of gravel 1680 kg/ m3. So, yields of 1 tonne of gravel = 1000/ 1,680 = 0.595m3.

**Conclusion:**

There are 0.595 cubic meter in a tonne of gravel. One tonne of gravel weighs 1000 kg. 1m3 of gravel weighs about 1,680 kg. So, yields of 1 tonne gravel in m3 = 0.595 cubic meter.
