Land Measurement & Conversion

Convert and calculate land area, dimensions, boundaries, and volumes for property planning.

These tools help landowners, real estate professionals, and DIYers work with property measurements. Whether you're converting acres to hectares, calculating irregular plot areas from GPS coordinates, or estimating fence requirements, each calculator shows its work with clear formulas. You might also find our Project land value over time, Calculate building allowances, Calculate contour areas, Calculate per-acre application rates, Convert other measurement units, Estimate fence materials, Advanced mathematical calculations and Calculate solar land requirements helpful for related calculations.

What you can do in Land Measurement & Conversion

•Convert between acres, hectares, square feet, square meters, bigha, rai, and other regional land units
•Calculate plot area from dimensions (length × width) or GPS coordinates with irregular shapes
•Estimate fence or boundary perimeter length from plot coordinates or manual measurements
•Check easement and right-of-way corridor areas for utility planning and access roads
•Verify frontage and setback compliance against zoning requirements
•Compute soil, topsoil, or mulch volumes for landscaping with waste factors and weight estimates

Accuracy, assumptions, and sources

•Unit conversions use exact mathematical relationships (1 acre = 43,560 sq ft = 4,046.8564224 m² exactly).
•Area calculations assume flat, planar surfaces. Sloped terrain has larger actual surface area than plan (horizontal) area.
•GPS-based calculations depend on the accuracy of your coordinates. Consumer GPS has ±3-5 meter typical accuracy.
•Fence length estimates show plan view (horizontal) distance. Add 5-15% for sloped terrain.
•Regional units (bigha, rai, tsubo) vary by locality. We use common standard values—verify local conventions.
•All calculations are for planning estimates. Legal land descriptions require licensed surveys.

If you're calculating easement or utility corridor area→Easement & Right-of-Way Estimator
If you need to check setback and buildable area→Plot Frontage & Setback Checker
If you're estimating soil or topsoil for landscaping→Soil Volume Calculator

Common mistakes to avoid

•Confusing plan area (horizontal) with surface area (actual ground). Sloped land has more surface area than shown on maps.
•Using consumer GPS coordinates for precise area calculations—errors compound and can significantly affect small plots.
•Forgetting to verify regional unit definitions. A 'bigha' in Bihar differs from a 'bigha' in Gujarat.
•Mixing up perimeter (fence length) with area. Doubling a plot's area doesn't double its fence requirement.
•Not accounting for setbacks and easements when calculating usable area. Gross area ≠ buildable area.
•Assuming fence length from four corner coordinates without checking if the boundary has jogs or curves.
•Using theoretical soil depth without accounting for compaction—loose fill settles 10-20% after placement.
•Ignoring significant figures. Converting 1.0 acre to sq ft (43,560) implies more precision than you likely have.

Editorial policy

✓All calculators provide educational estimates for land planning, not legal survey results.
✓Unit conversion formulas follow international standards (ISO, BIPM). Regional units use commonly accepted values.
✓We don't store your coordinates or measurements. All calculations run client-side in your browser.
✓For property transactions or legal matters, always hire a licensed surveyor.

Frequently Asked Questions

How accurate are the area conversion calculators?

Our converters use exact mathematical relationships between units. 1 acre = 43,560 sq ft = 4,046.86 m² exactly. Rounding only occurs at display time. For survey-grade work, verify with a licensed surveyor since field conditions introduce real-world variance.

Why do I get different results from my GPS app?

GPS coordinates have inherent accuracy limits (typically ±3-5 meters). Our calculators use the coordinates you provide exactly. Small coordinate errors compound when calculating areas. For precise land boundaries, use survey-grade GPS or professional surveys.

Can I calculate irregular plot areas?

Yes, our Irregular Plot Area calculator accepts multiple coordinate points or dimensions. Enter vertices in order around the boundary. More points give better accuracy for curved or complex shapes. The calculator uses the surveyor's formula for polygon areas.

What's the difference between gross and net acreage?

Gross acreage is the total land area within boundaries. Net acreage excludes easements, rights-of-way, setbacks, and unbuildable areas. Our calculators show gross area—subtract easements and restrictions separately for net usable area.

How do I convert between different land measurement systems?

Use our Land Area Converter for instant conversions between acres, hectares, square feet, square meters, bigha, rai, and other regional units. Enter a value in any unit and see all equivalents. We support common US, metric, and international land units.

Are fence length estimates accurate for uneven terrain?

Our Boundary Fence Length calculator measures horizontal (plan view) distance. For hilly terrain, actual fence material needed is longer due to slope. Add 5-15% for moderate slopes, more for steep terrain. Use our slope calculators to estimate adjustments.
