Rectangle Concrete Calculator
The rectangle is the workhorse of concrete work — slabs, pads, walks and floors. This rectangle concrete calculator multiplies length × width × thickness and converts to every ordering unit.
इस कैलकुलेटर का उपयोग कैसे करें
- अपने आयाम दर्ज करें — लंबाई के लिए फीट, मोटाई के लिए इंच.
- विकल्प समायोजित करें — अपव्यय प्रतिशत, बैग का आकार और आपके स्थानीय कंक्रीट की कीमत।
- अपने परिणाम पढ़ें — टाइप करते ही आयतन, बैग, वजन और लागत लाइव अपडेट होते हैं।

Rectangle volume = Length × Width × Thickness हल किया गया उदाहरण: A 12 × 10 ft pad at 4 in: 12 × 10 × 0.333 = 40 ft³ ÷ 27 ≈ 1.48 yd³ (≈ 1.13 m³).
Every concrete calculator rectangle computation reduces to three numbers, but unit slips cause most ordering errors — thickness measured in inches must become feet (divide by 12) before multiplying.
Rectangles also underpin composite estimates: L-shapes, U-shapes and stepped slabs are just rectangles added together. If your pour is several rectangles, run each here and sum, or use the irregular shape calculator.
Results include cubic feet, cubic yards, cubic meters and litres, plus bags by size, concrete weight and cost with your local price.
अक्सर पूछे जाने वाले प्रश्न
rectangle concrete calculator के बारे में सामान्य प्रश्न।
How do I calculate concrete for a rectangle?
Length × width × thickness in one unit. In feet: a 20 × 10 ft slab at 4 in is 20 × 10 × 0.333 = 66.7 ft³ ≈ 2.47 yd³.
Does it work in metric?
Yes — switch to metric and enter meters and centimeters; results show cubic meters and litres alongside imperial units.
What about non-rectangular pours?
Use the dedicated circle, triangle, trapezoid, octagon or L-shape calculators, or split any odd footprint into rectangles with the irregular shape calculator.
How much waste should I add?
5% for clean formed rectangles, 10% for pours on rough or sloping subgrade.
