So funktioniert es
- 1
Measure the length and width of the walkway in feet.
- 2
Measure the thickness in inches.
- 3
Multiply length × width × thickness (converted to feet) to get cubic feet.
- 4
Divide by 27 to convert to cubic yards.
(length * width * (thickness / 12)) / 27Häufig gestellte Fragen
How do I convert thickness from inches to feet?
Divide the thickness in inches by 12. For example, 4 inches = 4/12 = 0.333 feet.
Why divide by 27?
There are 27 cubic feet in one cubic yard (3 ft × 3 ft × 3 ft). Concrete is usually ordered by the cubic yard.
Should I order extra concrete?
It's common to add 5-10% for waste, spillage, or uneven subgrade. This calculator gives the theoretical volume.

Formeln
Die Mathematik hinter diesem Rechner, aufgeschrieben, damit Sie das Ergebnis überprüfen können.
Volume in cubic feet
Multiply length and width (in feet) by thickness converted to feet.
Example:
Input: L=10 ft, W=3 ft, T=4 in
Calculation: 10 × 3 × (4/12) = 10 cubic feet
Result: 10 ft³
Convert to cubic yards
Divide the cubic feet volume by 27 to get cubic yards.
Example:
Input: V=10 ft³
Calculation: 10 / 27 ≈ 0.37
Result: 0.37 yd³
Anwendungsfälle im Alltag
Wo diese Berechnung im täglichen Leben vorkommt.
Home walkway
Estimate concrete for a front or backyard path.
Example: 20 ft × 3 ft × 4 in ≈ 0.74 yd³
Garden path
Plan a narrow, decorative walkway.
Example: 15 ft × 2 ft × 3 in ≈ 0.28 yd³
Commercial sidewalk
Budget for a wider, thicker walkway.
Example: 50 ft × 5 ft × 6 in ≈ 4.63 yd³
Tipps und häufige Fehler
Tips
- Measure in feet for length and width, and inches for thickness.
- Round up to the nearest quarter yard when ordering.
- Add 5-10% extra for waste and uneven ground.
- Check local building codes for minimum thickness requirements.
Common Mistakes to Avoid
- Forgetting to convert thickness from inches to feet.
- Using square feet instead of cubic feet.
- Not dividing by 27 to get cubic yards.
Annahmen und Einschränkungen
- Use the stated inputs and units.
- Results are estimates for planning and education.
- Check measurements and source data before making an important decision.
