Quick Guide to Use This Calculator

  • Enter the volume of wet concrete to be produced in cubic meters.
  • Choose the concrete grade from the dropdown menu.
  • Select the water-to-cement ratio from the dropdown menu.
  • Click the “Calculate” button to obtain results.
  • To reset the form, click the “Reset” button.


  1. Dry volume of concrete in m3 = 1.54 * wet volume of concrete in m3
  2. Dry volume of cement = (cement ratio / sum of ratio) * wet volume of concrete in m3 * 1.54
  3. Dry volume of fine aggregate = (sand ratio / sum of ratio) * wet volume of concrete in m3 * 1.54
  4. Dry volume of coarse aggregate = (coarse ratio / sum of ratio) * wet volume of concrete in m3 * 1.54
  5. Weight of cement in kgs  =  Dry volume of cement in m3 * 1440 
  6. Amount of water needed = water to cement ratio * Weight of cement in kgs

Concrete Grade Ratio (Cement: Sand: Coarse)

  • M25 – (1:1:2)
  • M20 – (1:1.5:3) 
  • M15 – (1:2:4) 
  • M10 – (1:3:6)
  • M7.5 – (1:4:8)
  • M5 – (1:5:10)
