Cement Calculator
Calculate the exact amount of cement needed for your construction project. Estimate cement bags, cost, and requirements for concrete slabs, footings, and more.
Step 1: Project Dimensions
Understanding Cement Calculations
Cement quantity is calculated based on the volume of concrete needed. Standard concrete mix uses approximately 1 part cement, 2 parts sand, and 3 parts gravel by volume.
Step 2: Cement & Mix Details
About Concrete Mix Ratios
The mix ratio determines the strength and workability of concrete. Standard ratios range from 1:2:3 for general construction to 1:4:8 for mass concrete work. Always add a waste factor for spillage and uneven surfaces.

Cement Calculation Formula
Volume (yd³) = (Length × Width × Depth) / Conversion Factor
Cement bags = (Volume × Cement ratio × Density) / Bag weight. Standard concrete density is 150 lb/ft³. The conversion factor accounts for unit conversions (inches to feet, etc.).
