How to Convert Rai to Square Meters
Formula: Square Meters = Rai × 1,600
Examples:
- 0.5 Rai to m²: 0.5 × 1,600 = 800 m²
- 1 Rai to m²: 1 × 1,600 = 1,600 m²
- 2 Rai to m²: 2 × 1,600 = 3,200 m²
- 5 Rai to m²: 5 × 1,600 = 8,000 m²
Understanding "Rai-Ngaan-Wah" Notation:
Example: "2-3-50 rai" means:
- 2 Rai = 2 × 1,600 = 3,200 m²
- 3 Ngaan = 3 × 400 = 1,200 m²
- 50 Square Wah = 50 × 4 = 200 m²
- Total: 3,200 + 1,200 + 200 = 4,600 m²
