Calculation trace

  1. 4 m × 3 m × 0.1 m = 1.2 m³
    1.2 m³
    Volume in cubic metres
  2. 1.2 m³ ÷ 0.764554858 = 1.569541 yd³
    1.56954074 yd³
    Volume in cubic yards
  3. 1.2 m³ × 35.3146667 = 42.3776 ft³
    42.37760004 ft³
    Volume in cubic feet

How it works

Volume is length × width × depth in metres, giving cubic metres. It is also shown in cubic yards and cubic feet using the exact conversion factors (1 yd³ = 0.764554857984 m³).

Assumptions & limits

  • Assumes a simple rectangular pour; add an allowance for waste, spillage and uneven subgrade.
  • Outputs volume only — it does not estimate bags or mix ratios.

FAQ

How much extra concrete should I order?
A common allowance is 5–10% over the calculated volume for spillage and uneven ground; follow your supplier’s guidance.
