Gravel Calculator

Estimate volume, weight, and cost. Mass↔Volume price auto-convert via density.

Gravel Specification

Gravel type

Custom density

Density unit

Using density: —

How much gravel do I need?

Enter the dimensions of the rectangular area you want to fill with gravel.

Length

Width

Area

Area auto-calculates from Length×Width, or you can enter it directly.

Depth

Volume needed

Weight needed

How much will the gravel cost me?

Price per unit of mass

Currency

Price per unit of volume

Total cost

—

Edit either price; the other updates automatically using the current density & units.

Step-by-step derivation

—

References

Area: A = length × width
Volume: V = A × depth
Weight: W = ρ × V
Price coupling: (Currency/vol) = (Currency/mass) × ρ, with proper unit conversions
