How MAXScanner calculates results

One calculation owner per real intent

We prefer one canonical calculator for one mathematical relationship. Reciprocal operations such as VA ↔ watts or Ah ↔ Wh can live on one page when they are the same equation in reverse. A separate URL is created only when the user task, required inputs and useful outputs are meaningfully different.

• • This reduces keyword cannibalization.
• • It keeps maintenance and regression testing on one engine.
• • It prevents a large index of near-duplicate numeric pages from becoming the product.

Inputs belong to the person or the source data

Coverage, density, efficiency, power factor, package yield, waste allowance and similar values are not universal constants. Where those values vary by product or project, MAXScanner gives them an input instead of silently selecting a convenient number.

• • Paint coverage should come from the product label or technical data.
• • Concrete bag yield should come from the package.
• • Battery depth-of-discharge and conversion efficiency should match the actual system.
• • Electrical voltage basis and phase configuration are labeled explicitly.

Units and formulas stay visible

Results are calculated from the units named beside the inputs. Where two naming systems are commonly confused—such as MB vs MiB, PPI vs printer DPI, kW vs kVA or calendar days vs business days—the page keeps the distinction visible instead of converting silently.

Worked steps are generated from the same input values used by the live result so a visitor can reproduce the arithmetic independently.

Rounding happens at the real purchase boundary

Intermediate calculations keep more precision than the final display. We round upward only where the real-world object is indivisible, such as sheets, rolls, bags, boxes or pavers. Decimal formula results are not rounded upward just to look safer or more authoritative.

Dates use calendar arithmetic where the question is calendrical

Relative-date pages work with civil calendar dates rather than treating every date question as an elapsed number of milliseconds. Calendar-month additions clamp to valid month-end dates, and the exact “from today” pages refresh on a short revalidation window so their crawlable answer does not freeze at deployment time.

Safety boundaries are part of the result

A formula can calculate current without determining a safe conductor or protective device. A stair calculator can describe rise/run geometry without certifying code compliance. MAXScanner keeps those boundaries in the visible page copy and does not convert a basic formula into unsupported professional advice.
