Measure individual paint faces with their own openings and coats. Compare product-specific volume ranges, real containers, matching stock and optional cost.

Convert square meters to square feet. Area conversion for real estate and flooring. Free unit converter with precise, instant browser-based conversions — no

Calculate percentages in seven modes with visible formulas, strict input validation, signed percentage change, and symmetric percentage difference.

Calculate percentage, fixed, sale-price, and Buy-X-Get-Y discounts with whole-item bundle rules, sequential coupons, tax, quantity, and unit-price comparisons.

Calculate one observed price per explicit unit and preserve the consistent denominator, cost scope, and comparison limits that make the rate useful.

Reconcile measured hardwood areas, random-length inventory, actual carton coverage and whole-carton cost without assuming a fixed board count.

Compare whole-width carpet strips with four-wall trim, roll-edge loss and extra cut length. Inspect seam candidates and both run directions for one rectangular room.

Review laminate edge rows, starter lengths and joint spacing, then reconcile whole cartons, matching inventory and separately approved underlay.

Count fence posts from separate straight runs, reviewed maximum spacing and shared endpoint IDs. Reconcile gates, exact post SKUs, usable stock and whole sale packs.

Round separate net fence spans by exact installed product module, then reconcile reviewed post and gate schedules, matching stock, whole sale packs and incomplete quotes.

Plan measured stain surfaces and pass-specific coverage ranges. Reconcile exact product stock, real containers and optional quotes without invented railing or stair factors.

Calculate exact lumber board feet, a user-chosen planning allowance, and a price scenario from measured dimensions and whole-piece count.

Measure rectangular, circular and annular concrete groups with depth ranges, counts and voids. Reconcile exact bag yields or ready-mix terms and save source-owned planning records.

Build a measured multi-area takeoff, compare exact carton coverage with a reviewed source-tile count, and price whole packages after matching inventory.

Audit source-labelled flow, velocity, circular area and theoretical inside-diameter arithmetic against one already documented candidate ID—without selecting nominal pipe, material or compliance.

Reproduce one source-labelled electrical load schedule from connected volt-amperes and explicitly copied line multipliers—without choosing code factors or sizing a service, feeder, conductor or breaker.

Plan whole drywall sheets from measured wall and ceiling faces, openings, explicit allowance, exact selected sheet dimensions, and price.

Estimate appliance kWh and cost by day, week, average month, current calendar month, and year, with an optional regional CO₂ factor.

Compare documented annual electricity use for two appliances using one local rate, entered upgrade cost, and explicit planning horizon.
