Conversion formula and reference table
Exact formula: Value in Number of Tiles = Value in Room Area (sq ft) × 1.0000. Reverse: Value in Room Area (sq ft) = Value in Number of Tiles ÷ 1.0000.
| Room Area (sq ft) | Number of Tiles |
|---|---|
| 0.5 Room Area (sq ft) | 0.5000 Number of Tiles |
| 1 Room Area (sq ft) | 1.00 Number of Tiles |
| 2 Room Area (sq ft) | 2.00 Number of Tiles |
| 5 Room Area (sq ft) | 5.00 Number of Tiles |
| 10 Room Area (sq ft) | 10.00 Number of Tiles |
| 25 Room Area (sq ft) | 25.00 Number of Tiles |
Conversion accuracy and official sources
The conversion factor used — 1 Room Area (sq ft) = 1.0000 Number of Tiles — is sourced from: CPWD specifications, IS 456 (Plain and Reinforced Concrete), and BIS material standards.
Traditional Indian measurement units can vary between districts within the same state, between historical periods, and between formal (government-recorded) and informal (market-practice) usage. The factor used here represents the current officially notified standard.
Step-by-step verification guide
- Obtain official documents first. For land: retrieve Khasra-Khatauni from your state land records portal. For gold: request a BIS hallmark certificate. The area or weight will be stated in the traditional unit alongside the metric equivalent.
- Use calibrated instruments. For land: a licensed surveyor uses a standard Gunter chain (66 feet) or electronic total station. For gold and cooking: use a BIS-certified laboratory balance traceable to the National Physical Laboratory (NPL India).
- Verify boundary markers. Every registered plot has boundary pillars (dhaiya) at corners. Measure each boundary independently and verify against the document dimensions.
- Cross-check with the issuing authority. For any transaction above Rs 10 lakh, an official survey by the revenue department or a BIS-certified assayer is recommended before registration.
- Convert to metric for official submissions. All government filings (RERA, bank valuations, mutation) require metric units. Use the conversion this calculator provides for your official submission documents.
Common errors and how to avoid them
- Assuming a uniform standard across states. The Room Area (sq ft) varies significantly by state. Always confirm the state-specific standard before converting.
- Confusing similar-sounding units. Many Indian measurement units share similar names but differ widely in value. For example, Bihar Dhur (68 sq ft) and Tripura Dhur (3.6 sq ft) are entirely different despite the same name.
- Using outdated factors. Some older websites cite historical or regional variants. This calculator uses the current officially notified standard.
- Premature rounding. For property transactions, use full decimal precision. A rounding error of 0.1 Room Area (sq ft) on a 10-unit plot can represent a legally significant area.
- Not accounting for deductions. In land measurement, recorded area includes rights-of-way, water channels, and boundary widths. Usable (net) area is typically 95-98% of gross recorded area.
Frequently asked questions
How many 600x600 tiles for 100 sq ft?
100 sq ft requires approximately 18 tiles of 600x600mm (6.45 sq ft each), plus 10% wastage = 20 tiles.
