Divide by 27 to convert to cubic yards.
(length * width * (thickness / 12)) / 27Часто задаваемые вопросы
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.

Формулы
Математика, лежащая в основе этого калькулятора, изложена так, чтобы вы могли проверить результат.
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
Примеры из реальной жизни
Где этот расчет встречается в повседневной жизни.
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
Советы и частые ошибки
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.
Допущения и ограничения
