Architect's Formulator

ARCHITECT'S FORMULATOR is the ultimate professional calculator for architects,
   engineers, and construction professionals — with over 2,000 formulas in a
  single app.

  Whether you're sizing beams, designing HVAC systems, calculating voltage
  drops, or checking ADA compliance, Architect's Formulator covers every
  discipline — structural, electrical, mechanical, plumbing, and carpentry —
  plus unit conversions, reference tables, and ADA accessibility resources.

  ARCHITECTURE & STRUCTURAL — 29 categories covering beam loads across single
  through four continuous spans, concrete design, flat plate analysis, steel
  design, masonry, environmental loads (wind, snow, seismic), foundation and
  retaining walls, wood design, acoustic absorption, 100+ material weights, fire
   egress, roof drainage, solar/daylighting, thermal performance, site grading,
  cost estimating, and more.

  ELECTRICAL — 15 categories for AC/DC circuits, Ohm's Law, motors,
  transformers, voltage drop, wiring/conduit sizing, batteries, impedance, power
   demand, lighting design, UPS sizing, and operating costs.

  CARPENTRY — 8 categories for lumber, stairs, safe beam loads, wall loads,
  roofing (shed, gable, hip), railing/deck framing, crown molding, and materials
   estimation for drywall, concrete, paint, and plywood.

  PLUMBING & HVAC — 29 categories covering pipe sizing, water flow, pumps,
  boilers, and a comprehensive HVAC library including airside/waterside heat
  transfer, duct sizing, fan and pump laws, gas laws, psychrometrics,
  refrigeration, heating/cooling load design, energy content for 16 fuel types,
  ventilation rates per ASHRAE 62.1, and steam/hydronic systems.

  CONVERSIONS — 17 categories with 500+ conversions for pressures, flows, BTU,
  horsepower, watts, frequency, linear/liquid/square/cubic measures, weights,
  and a Metric library with 280+ conversions across length, area, volume, mass,
  energy, power, and more.

  TEMPERATURE SCALES — Convert between all 8 scales: Celsius, Fahrenheit,
  Kelvin, Rankine, Réaumur, Newton, Delisle, and Rømer.

  REFERENCE TABLES — IBC Occupancy Loads, Brick Sizes, Lumber Dimensions, AWG
  Wire Gauge, Concrete Mix Ratios, and Insulation R-Values.

  ADA REFERENCE — 50 illustrated diagrams for wheelchair clearances, ramps, grab
   bars, elevators, accessible parking, and restroom layouts, plus 17 PDF
  documents with full ADA guidelines.
