    How this calculator works

    • One 50 kg cement bag is taken as 1.25 cubic feet.
    • Dry volume = wet volume × 1.54 for concrete (1.33 for mortar).
    • Cement = dry volume × cement part ÷ total parts.

    Frequently asked questions

    Roughly 0.2 bag (about 10 kg). Use the calculator for the exact figure including wastage.

    A 1:2:4 mix is common for slabs and beams, but the correct grade must come from your structural engineer.
