Formula & Legal Details
• Rectangular Area = Length × Width • Triangle (Heron's Formula): s = (a+b+c)/2, Area = √(s(s-a)(s-b)(s-c)) • 4-Side Average Formula: Area = ((North+South)/2) × ((East+West)/2) • 1 Hat = 1.5 ft · 1 Gaz = 3 ft · 1 Link = 0.66 ft • Area (sq ft) ÷ 435.6 = Decimal / Shotok
Conversion Table
| From Unit | To Unit | Conversion Ratio / Value |

Frequently Asked Questions (FAQ)
For standard land survey, measure all 4 sides in feet, average opposite sides: Average Length = (Length1 + Length2)/2 and Average Width = (Width1 + Width2)/2, then multiply Average Length × Average Width = Total Sq Ft. Divide by 435.6 to get Shatak/Decimal.
