Tonnage can be derived from volume.
Volume is calculated in m3 (length x width x depth).
1 m3 = 1.5t – 2.2t of crushed stone depending on the grading and degree of compaction.
2.1 tonnes of Type 1 = 1m3
1m3 of well compacted scalpings is heavier than 1m3 of 75mm clean stone, (consider the amount of air spaces!)
1 inch = 2.54cm or 0.0254m 1ft = 0.3048m
1 cubic yd = 0.7646m3 1yard = 0.9144m
