FAQ
Frequently asked questions
What density should I use for gravel?
It varies by type and compaction, but 1,600-1,800 kg/m³ is a common range for crushed stone gravel.
Should I add extra for compaction?
Many suppliers recommend ordering 5-10% extra, since gravel settles after placement.
Can I use this for sand or mulch too?
Yes, just change the density value to match your material.
What units does the weight come out in?
Kilograms, based on the density figure you provide.
