Questions & answers
What does Gravel Mass Calculator calculate?
Estimate aggregate mass from area, depth and your supplied bulk density.
Which units should I enter?
Area uses square meters. Depth uses centimeters. Bulk density uses kilograms per cubic meter. Convert values to these units before calculating.
Which formula does it use?
Mass = area × depth in meters × bulk density.
What does the included example show?
Area: 20 square meters; Depth: 8 centimeters; Bulk density: 1600 kilograms per cubic meter. Result: Volume · cubic meters = 1.6; Mass · kilograms = 2560; Mass · metric tonnes = 2.56.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
