About Converting Square Hectometers to Ares
Comparing Square Hectometer and Are is common in agriculture and real estate, where US land is typically measured in acres and most of the rest of the world uses hectares. Specifically: Square metric area unit, and an are is 100 square meters.
Formula
ares = square hectometers × 100
This factor comes from each unit's defined relationship to the category's base unit: 1 square hectometer equals 10000 base units, and 1 are equals 100 base units, so dividing one by the other gives the direct square hectometer-to-are factor of 100.

1 hm2 × 100 = 100 a
1 square hectometer = 100 ares.
Real-world example
10 hm2 × 100 = 1,000 a
10 square hectometers = 1,000 ares.
