Gravel Calculator (Cubic Yards & Tons)
Gravel calculator: cubic yards and tons of gravel, crushed stone or sand for a driveway, path or patio base.
V = L · W · d
How to use this calculator
- Choose the quantity you want under “Solve for”.
- Type the known values and pick their units: any combination works.
- The result updates as you type. Open “Show the steps” to see the substitution.
Volume = length × width × depth. Gravel weighs about 1.6 t/m³ (1.35 US tons per yd³); order 10 % extra for compaction.
Formula
V = L · W · d
| Symbol | Quantity | Units |
|---|---|---|
| L | Length | m, km, cm, mm, µm, nm, pm, Å, in, ft, yd, mi, nmi, au, ly |
| W | Width | m, km, cm, mm, µm, nm, pm, Å, in, ft, yd, mi, nmi, au, ly |
| d | Depth | m, km, cm, mm, µm, nm, pm, Å, in, ft, yd, mi, nmi, au, ly |
| V | Volume | L, mL, µL, m³, dm³, cm³, gal, gal (UK), qt, pt, cup, fl oz, ft³, yd³, in³ |
Constants used: Gravel ≈ 1.6 t/m³ (≈ 1.35 US tons per yd³)
Worked example
Given: L = 32.8084 ft · W = 9.84252 ft · d = 1.9685 in
V = L W d
Result: V = 1.96193 yd³
Volume for different values of Length
| L · Length | V · Volume |
