MONUMAKE Calculators

MONUMAKE Calculators is a set of practical metric calculations for construction — for designers, site managers, tradespeople and self-builders. All calculations are free, work offline and need no sign-up. CONSTRUCTION ASSEMBLIES • Layers with thickness, λ and density • Thermal resistance R, U-value, total thickness and weight • Save multiple assemblies STAIRCASE • Number and height of risers from the floor-to-floor height • Checked against the rules of the selected country: Czechia (ČSN 73 4130), Slovakia, Germany (DIN 18065), Poland, France, Italy, Spain • Step rule 2h + b, riser, going and pitch; stairs inside a dwelling or common stairs • Pitch and length of the flight, headroom clearances LAND PLOT & REGULATIONS • Plots and their areas • Site coverage, green area ratio with paved areas, floor area ratio (FAR), rainwater infiltration, minimum plot size, height limits • Turn each regulation on or off to match your zoning plan • PASS / FAIL assessment, multiple saved options CALCULATIONS • Rule of three • Volume and area of a cylinder • Roof height and pitch (in % and degrees) • Linear interpolation of height • kW ↔ A with a recommended breaker (230 V / 400 V) CONVERSIONS • a·10ⁿ notation ↔ decimal number • kN ↔ kg, degrees ↔ %, °C ↔ °F SPECIAL • Air humidity: dew point, absolute humidity, whether ventilating helps, mould and surface condensation risk • Thermal expansion of materials • Running cost of an appliance PREMIUM (one-time purchase, no subscription) • Export assemblies, staircases and plot regulations to PDF with your name as the preparer • Export individual proposals to a file • Unlimited saving (5 assemblies, 5 staircases and 5 land plots are free) The full data backup stays free. On tablets and iPad, calculators open next to the list — a layout made for the big screen. No account, no ads, no tracking. Your data stays only on your device. Calculation results are indicative and do not replace project documentation or a professional assessment. Always verify them against the applicable standards and regulations.
