📖 How to Calculate Bajri & Sand CFT (Step-by-Step Formula)
In Pakistan's construction industry, raw building materials such as Margalla Crusher Bajri, Sargodha Crush, Chenab Sand (Rait), Dina Sand, and Kassu are priced and sold by volume in Cubic Feet (CFT).
If your measurements are taken in feet and inches, convert the inches to decimal feet by dividing by 12, or convert the entire measurement to inches and divide the cubic inches by 1,728.
Volume (CFT) = Length (Feet) × Width (Feet) × Depth/Height (Feet)
Formula in Inches:
Volume (CFT) = [ Length (Inches) × Width (Inches) × Height (Inches) ] ÷ 1,728
🚛 Pakistan Vehicle CFT Capacity & Weight Reference Table
This reference matrix provides standard interior bed dimensions, CFT capacity, and estimated metric tonnage for common aggregate transport vehicles in Pakistan:
| Vehicle Type | Bed Dimensions (L × W × H) | Volume (CFT) | Est. Weight (Tons) | Common Material |
|---|---|---|---|---|
| Suzuki / Shahzore Pickup | 10 ft × 5.5 ft × 2.25 ft | 120 – 135 CFT | 5.2 – 5.8 Tons | Small residential Bajri / Sand |
| Tractor Trolley | 12 ft × 6 ft × 3.5 ft | 250 – 280 CFT | 11.0 – 12.2 Tons | Local crushed stone & Kassu filling |
| 6-Wheeler Dumper (Single Axle) | 14 ft × 7 ft × 4.0 ft | 380 – 420 CFT | 16.5 – 18.2 Tons | Commercial construction supplies |
| 10-Wheeler Dumper (Tandem Axle) | 18 ft × 7.5 ft × 5.5 ft | 700 – 750 CFT | 30.4 – 32.6 Tons | Quarry-direct Margalla / Sargodha Bajri |
| 12-Wheeler / 10-Ton Bed Trailer | 22 ft × 8.0 ft × 6.0 ft | 1,000 – 1,100 CFT | 43.5 – 47.8 Tons | Megaproject bulk aggregate supply |
⚖️ Converting CFT to Weight in Tons (Material Density Guide)
While Bajri and sand are measured in volume (CFT) at construction sites, stone crushers and highway weighbridges (*Kaanta*) weigh trucks in Metric Tons. On average, 1 CFT of crushed stone equals 43.5 kg.
| Aggregate Type | Average Density (kg / CFT) | CFT per Metric Ton | Weight Factor (Tons/CFT) |
|---|---|---|---|
| Margalla Crusher Bajri (1/2" & 3/4") | 43.5 kg / CFT | 23.0 CFT / Ton | 0.0435 |
| Sargodha Crusher Bajri | 44.0 kg / CFT | 22.7 CFT / Ton | 0.0440 |
| Chenab Sand / Ravi Rait | 46.0 kg / CFT | 21.7 CFT / Ton | 0.0460 |
| Kassu / Plot Filling Soil | 48.0 kg / CFT | 20.8 CFT / Ton | 0.0480 |
🛡️ Pro Tips: How to Avoid Shortage & Cheating When Buying Bajri
Construction buyers in Pakistan often suffer a 10% to 15% volume loss due to improper measurement practices. Follow these rules when receiving a dumper or trolley:
1. Flatten Uneven Heaps: Drivers often heap aggregate in the middle while leaving corners empty. Level the top surface before measuring height.
2. Watch Out for Sand Bulking: Wet sand expands up to 20% in volume due to moisture surface tension without adding extra dry material. Always inspect moisture content.
3. Check Bed Floor Inclination: Ensure the dumper bed is lowered completely flat. A raised bed distorts height measurements.
