About Converting Square yards to Hectares
Comparing Square yard and Hectare 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. Square yard is typically associated with united States and United Kingdom (carpeting, landscaping, small land parcels), while Hectare is typically associated with used worldwide, especially in agriculture, forestry, and land statistics outside the US.
Formula
hectares = square yards × 0.000083612736
This factor comes from each unit's defined relationship to the category's base unit: 1 square yard equals 0.83612736 base units, and 1 hectare equals 10000 base units, so dividing one by the other gives the direct square yard-to-hectare factor of 0.000083612736.
Simple example
1 yd2 × 0.000083612736 = 0.0000836127 ha
1 square yard = 0.0000836127 hectares.
