Topsoil Calculator: Your Essential Gardening Companion

What is a Topsoil Calculator?

A digital tool that computes the amount of topsoil required based on project dimensions (length/width/depth) and preferred measurement units. It eliminates guesswork in gardening and ensures cost-effective soil purchases.

Calculation Formula

Volume = Length × Width × Depth

Metric: m³ (meters) | Imperial: yd³ (yards) or ft³ (feet)
Conversion: 1 yd³ = 27 ft³ | 1 m³ ≈ 1.31 yd³

How to Use

  1. Measure your area’s length and width
  2. Determine desired soil depth:
    • Lawn: 4-6 inches (10-15cm)
    • Garden beds: 8-12 inches (20-30cm)
  3. Select preferred units (metric/imperial)
  4. Get instant volume results with weight estimates
