About Calculator Street

Calculator Street (CalculatorSt.com) is a complete construction and home-improvement calculator platform — focused, accurate and private. We cover concrete, gravel, rebar, masonry, roofing, flooring, framing, decking, fencing, landscaping, asphalt and more. Every calculator is hand-verified for US customary and metric units, with clear formulas, worked examples and waste-aware estimates.

Founded 2026 by Vipul Otari — civil DIY enthusiast focused on US customary units, material densities and waste-aware estimating. Every calculation is verified against supplier scale-house densities and public specs (TxDOT compaction, CPSC playground). Last updated: 2026-08-28.

Vipul Otari — Author & Lead Reviewer

Built and reviewed every calculator. Mathematical models, example tables and construction assumptions are derived from established engineering references (ACI, CRSI, CMHA, NIST SP 811) and manufacturer product yields (such as QUIKRETE 80-lb concrete = 0.60 ft³). Contact for technical feedback or corrections: hello@calculatorst.com.

Editorial standard: Calculations are verified against manufacturer technical specifications, ASTM standards, and public transportation engineering data.

Our principles

  • Client-side computing — all math and dimensional conversions execute locally in your browser. Your measurements and cost inputs are never sent to our servers.
  • US & Metric standards — feet, inches, yards, and short tons (2,000 lb), with precise SI metric equivalents based on NIST SP 811 international conversion factors.
  • Mobile-first — large inputs, thumb-friendly, works on the job site at 320px. No horizontal scroll.
  • Transparent — every page shows formulas, examples, assumptions and related calculators. Cite sources: TxDOT compaction, CPSC playground.

How we verify

densities: pea 1.35, crushed 1.40, limestone 1.60 tons/yd³ verified vs scale house averages; concrete bag yields per manufacturer; roof multiplier √(pitch²+144)/12. Waste recommendations from field practice: 10% rectangle, 15% curves/hips.

Library

The platform now includes a complete library of construction and home-improvement calculators — organized into sixteen focused categories and searchable from any page. Every calculator is a standalone, indexable tool with its own formula, example, diagram and related tools.
