Brass Calculator — Convert Brass to Sq Ft, CFT, kg & Bricks

The brass calculator is an essential construction tool used across India for estimating earth, sand, gravel, and brick quantities. If you’ve been wondering how many sq ft is 1 brass, how is brass calculated in construction, how much for 1 kg of brass metal, how to calculate kg to brass, need a brass calculator app equivalent on mobile, or want a brass calculator for brick estimation — this free tool covers all of it. The “brass” unit (100 cubic feet) is widely used in Indian civil engineering, especially in UP, Bihar, Rajasthan and MP for earthwork and material procurement.

How To Use

Step-by-Step: How to Use the Brass Calculator

Choose Conversion Mode

Select from three tabs: “Brass to Others” for converting brass quantity to CFT/m³/kg, “CFT to Brass” for converting cubic feet or cubic meters to brass, or “Bricks in Brass” for brick estimation.

Enter Quantity & Material

Enter your brass quantity and select the material type (Sand, Gravel, Earth etc.) for weight calculation. Each material has a different bulk density — selecting the right one gives accurate kg and tonne results.

Click Convert / Calculate

Get instant results including CFT, cubic meters, weight in kg and tonnes. For the brick mode, see exact number of bricks needed for the given brass volume including mortar allowance.

Use for Procurement

Use the results for material orders, lorry load estimation (1 lorry ≈ 2–3 brass), and construction quantity surveying. 1 brass = 100 CFT = 2.832 m³ — the standard Indian construction unit.

Formula

Brass Calculation Formula Explained

1 Brass = 100 Cubic Feet (CFT) = 2.832 Cubic Meters (m³)

Brass to CFT: CFT = Brass × 100
Brass to m³: m³ = Brass × 2.832
Brass to kg (Sand): kg = Brass × 2.832 × 1600 = Brass × 4531.2
CFT to Brass: Brass = CFT ÷ 100
How many sq ft is 1 brass? 1 Brass = 100 sq ft (if 1 ft deep) or varies with depth
Bricks per brass: ≈ 500 bricks per brass (standard 9×4.5×3″ brick with mortar)

FAQ

Brass Calculator — People Also Ask

How many sq ft is 1 brass?

1 Brass = 100 Cubic Feet (CFT). If we consider 1 foot depth, then 1 brass covers 100 sq ft. If the depth is 6 inches (0.5 ft), then 1 brass covers 200 sq ft. The relationship between brass and sq ft always depends on the depth: Sq Ft = (Brass × 100) ÷ Depth in feet. So 1 brass ≠ a fixed sq ft value — it depends on how deep you’re filling or excavating.

How is brass calculated in construction?

Brass in construction is calculated as: Brass = Volume in CFT ÷ 100, or Brass = Volume in m³ ÷ 2.832. To find volume in CFT: multiply Length (ft) × Width (ft) × Depth (ft). For example, an excavation of 20ft × 10ft × 5ft = 1000 CFT = 10 Brass. One lorry (truck) typically carries 2–3 brass of material depending on the vehicle size.

How many bricks are in 1 brass?

For standard Indian bricks (9×4.5×3 inches) with 0.5 inch mortar: approximately 450–500 bricks per brass. The exact number depends on brick size and mortar thickness. Our brass calculator for brick mode calculates this precisely for any brick dimension you enter. For modular bricks (10×5×3 inches), the count is approximately 380–420 per brass.

How to convert kg to brass for sand?

To convert kg of sand to brass: Brass = kg ÷ (Density in kg/m³ × 2.832). For river sand (density 1600 kg/m³): 1 brass = 1600 × 2.832 = 4531 kg ≈ 4.5 tonnes. So to convert: Brass = kg ÷ 4531. Example: 9000 kg of sand = 9000 ÷ 4531 = approximately 2 brass. Use the CFT to Brass tab in our calculator for reverse conversion.
