Example: converting farmland size
A 3-hectare farm covers 30,000 m². Dividing by 1,600 gives 18.75 Rai. In Thai mixed units, the 0.75 Rai remainder is 3 Ngan, so the same area can be understood as 18 Rai 3 Ngan.
This makes it easier to compare a metric agricultural listing with neighboring Thai listings that use Rai.
Precision and comparison tips
- Hectare and acre are different units; do not use the acre-to-Rai factor for hectares.
- Because 1 hectare = 6.25 Rai exactly, extra decimal noise is unnecessary for ordinary comparisons.
- When comparing price per hectare with price per Rai, convert both the area and the price basis to the same unit.
