How this is calculated
Formula
- Convert ft → m if imperial is selected
- wet_volume = L × W × D
- dry_volume = wet_volume × 1.54
- Split dry volume by grade ratio → cement, sand, aggregate
- sand/agg shown in cft (× 35.3147)
- cost = bags × ₹/bag + (sand_cft + agg_cft) × ₹/cft
Assumptions
- Choose Metric (m) or Imperial (ft) for length, width, and depth.
- Volume = length × width × depth (converted to metres internally).
- Material split uses selected nominal grade mix and dry volume × 1.54.
- Cement bags are 50 kg standard Indian bags.
- Cost = (cement bags × ₹/bag) + ((sand + aggregate) cft × ₹/cft).
