Architecture

Architectural scale conversion, room volume for HVAC sizing, cylinder volume for columns and tanks, and mixed-unit math. For architects, drafters, and students.

Quick check

Drafting

Scale converter 1:100 · 50 mm = 5 m Mixed units 3′7″ + 5 cm = 1.14 m

Geometry

Room volume 4×3×2.5 m = 30 m³ Cylinder volume Ø30 cm × 2 m = 141 L Right triangle 3² + 4² → 5 Floor area 12 × 10 = 120 ft² Acreage 43 560 ft² = 1 ac

What this is

A focused set of architectural calculators — pure geometry and dimensional math. No materials, no project planning (that lives on our companion site RenoSheets). Each tool runs entirely in your browser, encodes its inputs in a shareable URL, and shows its math.

Reference only

These calculators are geometric references, not structural engineering. Structural sizing of beams, columns, slabs, and connections requires a sealed drawing reviewed by a qualified engineer or contractor working from the local building code.
