4 Tools

Finishing & Coating№ 06.01

Wall Paint Quantity & Can Requirement Calculator

Calculates total wall surface area minus window and door cutouts to determine the exact liters of paint and number of standard cans required.

Room Length & WidthWall HeightNumber of Doors & WindowsNumber of CoatsCoverage per Litre (m²/L)

Liters = [(Gross Wall Area − Openings Area) · Number of Coats] / Spread Rate (m²/L)Launch

Masonry & Flooring№ 06.02

Tile & Flooring Quantity Calculator (with Wastage Margin)

Computes the total number of ceramic or porcelain floor/wall tiles and required cartons needed, accounting for cutting wastage and room perimeter corners.

Room Length & Width (ft or m)Tile Dimensions (e.g. 600×600 mm, 2×2 ft)Wastage Allowance (5 - 15%)Tiles per Box

Tiles Needed = ⌈(Floor Area / Single Tile Area) · (1 + Wastage%)⌉Launch

Masonry & Flooring№ 06.03

Concrete Slab & Cement Mix Ratio Calculator

Determines total concrete volume in cubic meters/yards and decomposes it into required bags of cement, sand tons, and coarse aggregate according to mix ratios (e.g. M20 1:1.5:3).

Slab Length, Width & ThicknessMix Ratio (M15 1:2:4, M20 1:1.5:3)Cement Bag Size (50kg)

Wet Vol = L·W·T ; Dry Vol = Wet Vol · 1.54 ; Cement = Dry Vol · (Mix_Cement / ΣMix_Parts)Launch

Residential Energy№ 06.04

Electricity Bill & Appliance Power Consumption Estimator

Computes monthly electrical energy consumption in kilowatt-hours (kWh) from appliance wattage and daily operating hours, modeling tiered slab utility billing.

Appliance Wattage (W)Hours Used per DayDays per MonthElectricity Tariff per Unit (kWh)

Monthly kWh = Σ(Wattsᵢ · Hoursᵢ · 30) / 1000 ; Bill = Σ(kWh in slab · Slab Rate) + Fixed ChargeLaunch
