Cement Conversion FAQ
Everything you need to know about converting cubic metres to tonnes, calculating volumes, and ordering cement.
On average, 1 cubic metre of bulk Portland cement weighs approximately 1.44 to 1.50 tonnes. The exact weight depends on how compacted the cement powder is and its specific type.
The formula is: Weight (tonnes) = Volume (cubic metres) × Density (tonnes per cubic metre). For standard bulk Portland cement, the density is typically 1.44 tonnes/m³.
Yes. Damp or wet cement will weigh more than dry cement because water adds weight. However, moisture also causes cement to clump, harden prematurely, and lose its structural integrity, so it must always be stored in a strictly dry environment.
Measure the length, width, and desired depth of the area in metres. Multiply these three dimensions together (Length × Width × Depth) to get the total volume in cubic metres (m³). Note: this gives the volume of the final concrete, so you must factor in your specific mix ratio (e.g., 1:2:3) to find the exact cement portion required.
