Engineering tools made for Nepal
These tools use the units and practices common on Nepali sites and offices: ropani-aana-paisa-daam and bigha-kattha-dhur for land, 50 kg cement bags, cft for sand and aggregate, the Bikram Sambat calendar, and lakh-crore number formatting. Every calculator runs in your browser, so it works quickly even on a slow mobile connection, and the PDF and image tools never upload your files.
Quantities and costs from the construction calculators are estimates for planning and budgeting. Final quantities should come from approved drawings and a proper estimate prepared by an engineer.
