Calculatrice vérifiée avec une formule transparente
Concrete Gutter Calculator.
Estimates the volume of concrete needed to fill a concrete gutter based on its length, width, and depth.
Vos entrées
Comment ça marche
- 1
Convert width and depth from inches to feet by dividing by 12.
- 2
Multiply length (ft) by width (ft) and depth (ft) to get volume in cubic feet.
- 3
Optionally divide by 27 to get cubic yards.
- 4
Round to two decimal places for the final estimate.
length * (width/12) * (depth/12)Questions fréquentes
How do I account for waste or spillage?
Add 5-10% to the calculated volume to cover waste, uneven surfaces, or over-excavation.
Can I use this for a trapezoidal gutter?
This calculator assumes a rectangular cross-section. For trapezoidal shapes, use the average width (top + bottom divided by 2) as the width input.
What if my measurements are in meters?
Convert meters to feet first (1 m = 3.28084 ft) or use a metric version. This calculator works in feet and inches.

Formules
Les mathématiques derrière cette calculatrice, écrites pour que vous puissiez vérifier le résultat.
Rectangular Volume
Volume equals length times width times depth, all in consistent units.
Example:
Input: L=20 ft, W=1 ft, D=0.5 ft
Calculation: 20 × 1 × 0.5
Result: 10 cu ft
Cas d'utilisation réels
Où ce calcul apparaît dans la vie quotidienne.
Residential driveway gutters
Estimate concrete for a small gutter along a driveway or walkway.
Example: Typical 20 ft long, 12 in wide, 6 in deep.
Commercial drainage channels
Plan concrete for longer gutter runs on commercial properties.
Example: 50 ft long, 18 in wide, 8 in deep.
DIY landscaping projects
Calculate concrete for decorative or functional garden gutters.
Example: 10 ft long, 10 in wide, 4 in deep.
Conseils et erreurs courantes
Tips
- Always measure the actual dimensions after excavation, not just the planned ones.
- Order 10% extra concrete to avoid running short.
- Use a concrete calculator for irregular shapes by breaking them into rectangles.
- Check local building codes for minimum gutter sizes.
Common Mistakes to Avoid
- Forgetting to convert inches to feet before multiplying.
- Using the outer dimensions instead of the inner cavity dimensions.
- Not accounting for the slope of the gutter, which can slightly increase volume.
Hypothèses et limites
- Use the stated inputs and units.
- Results are estimates for planning and education.
- Check measurements and source data before making an important decision.
