The formula
To convert square feet to hectares, multiply the area in square feet by 0.000009290304:
hectares = square feet × 0.000009290304
A worked example
Say you have a 50,000 square foot site and want its size in hectares:
50,000 × 0.000009290304 = 0.4645152 hectares
So a 50,000 square foot site is just under half a hectare.
Why the number is exact
This factor is built from two exact definitions. A square foot is exactly 0.09290304 square meters (because one foot is exactly 0.3048 meters, squared), and a hectare is defined as exactly 10,000 square meters. Divide 0.09290304 by 10,000 and you get exactly 0.000009290304 hectares per square foot. Both pieces are exact, so the conversion is exact too — the answer never needs rounding at the source.
When you'll use it
Sizing farmland, development sites, parks, and solar or industrial plots, reading planning and environmental documents that use hectares, and comparing a US area quoted in square feet against international land measured in hectares.
