Square Meters to Cubic Meters Converter
Convert area (m²) to volume (m³) by specifying height or thickness. Ideal for construction estimation (concrete, mulch, flooring) and logistics.
About
Converting a two-dimensional area (Square Meters) to a three-dimensional volume (Cubic Meters) is physically impossible without a third variable: Thickness (or Height). This calculation is a daily necessity in construction, landscaping, and shipping. For example, knowing the floor area of a room is not enough to order concrete; one must know the slab thickness.
This tool bridges the gap by requiring the thickness input. It handles the unit conversion internally, allowing you to enter the area in meters but the thickness in millimeters or centimeters (common for flooring or mulch), ensuring the final volume is accurately calculated in cubic meters (m³). Incorrectly estimating this volume can lead to costly material shortages or waste on job sites.
Formulas
The formula extends a 2D plane into 3D space. The critical step is normalizing units so that Thickness matches the Area unit (meters).
If height is in millimeters:
