Estimate paint for walls (excluding ceiling). Wall area = 2 × height × (length+width). 1 liter covers ~10 m². Add 10% for waste.
💡 Subtract doors/windows area for accuracy.Calculate how many tiles needed for a floor. Each tile area = length×width (converted to m²). Add waste for cuts and breakage.
💡 Always buy 5‑10% extra tiles.Estimate how many planks or boards needed for a rectangular floor. Total area / plank area + 10% waste.
💡 Consider installation pattern (diagonal requires more).Calculate floor area of a rectangle. Length × width. Essential for flooring, tiles, or rugs. For irregular shapes, divide into rectangles.
💡 Measure in meters for easy conversion.Calculate volume of a rectangular space (length×width×height). Useful for concrete, air conditioning, or storage capacity.
💡 For cylinders or complex shapes, use specialized formulas.Volume needed for a slab or footing. Length × width × depth. Add 10% for waste and uneven ground. One m³ ≈ 2.4 tonnes.
💡 Order slightly more to avoid shortages.Estimate rolls needed for a wall. Wall area / (roll width × roll length). Add 10‑15% for pattern matching.
💡 Check pattern repeat for more accurate waste.Estimate cost of running an appliance. kWh = watts × hours / 1000. Multiply by price to get cost.
💡 Use sleep mode or timers to save energy.Estimate cooling capacity needed. Base: 600 BTU per m². Multiply by height factor and sun exposure.
💡 For rooms with many electronics or people, add 10-20%.
