Square Meters to Cubic Meters Converter & Cost Calculator
Calculate volume from area by adding thickness. Essential for construction budgeting (concrete, soil, timber).
About
In construction and materials procurement, a strictly 2-dimensional area measurement is rarely sufficient. Purchasing concrete, topsoil, or insulation requires a 3-dimensional volume calculation. This tool functions as a logic engine to bridge the gap between Area (m2) and Volume (m3) by integrating the critical "Height" or "Thickness" variable.
Miscalculating volume by failing to account for unit mismatches (e.g., area in meters but thickness in centimeters) leads to material shortages or expensive waste. This calculator enforces unit consistency and provides an immediate financial estimate, allowing project managers to visualize the total cost alongside the physical volume requirements.
Formulas
The core principle is the extrusion of a 2D plane into 3D space. The user inputs Area (A) and Thickness (h). The system standardizes h to meters before calculation.
If thickness is provided in centimeters or millimeters:
Total Cost (C) is calculated as:
