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.
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.
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).
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.
