Scale, measure, and calculate with ArchMM. A practical calculator for designers, model makers, builders, architects, and students—built around feet, inches, fractions, and architectural scale. MODEL SCALE Convert full-size feet and inches to model millimeters for 3D printing and model making, or work backward from a model measurement. Choose 1:1 or common architectural scales and compare the converted length with a printer-bed preset. CARPENTER CALCULATOR Use dedicated number, unit, fraction, and arithmetic buttons. Add and subtract dimensions, multiply lengths into area or volume, recall memory, and revisit recent calculations. The next number after equals starts a new calculation. SCALE TO INCHES Enter a full-size measurement and get its scaled size in inches. Change the drawing scale at any time. PROJECT TOOLS Calculate board feet, explore a stair layout, and work out common-rafter geometry. Each tool explains its assumptions.
