Review Process & Methodology

Every calculator is verified for clarity, correctness, and practical assumptions (coverage rates, density values, yield per unit, and recommended overage). We continuously compare outputs against real-world examples and update formulas as standards evolve.

  • Formulas documented with sources and unit definitions
  • Edge cases tested (irregular shapes, fractional units, rounding)
  • Assumptions disclosed on each tool’s page
  • Change logs and last-reviewed dates maintained
