About Converting Square Nanometers to Square feet
Comparing Square Nanometer and Square foot 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 a square foot is exactly 0.09290304 square meters.
Formula
square feet = square nanometers × 1.076391e-17
This factor comes from each unit's defined relationship to the category's base unit: 1 square nanometer equals 1e-18 base units, and 1 square foot equals 0.09290304 base units, so dividing one by the other gives the direct square nanometer-to-square foot factor of 1.076391e-17.
Simple example
1 nm2 × 1.076391e-17 = 1.076391e-17 ft2
1 square nanometer = 1.076391e-17 square feet.
Real-world example
10 nm2 × 1.076391e-17 = 1.076391e-16 ft2
10 square nanometers = 1.076391e-16 square feet.

History of the Square foot
The square foot follows directly from the foot, standardized in England over centuries and fixed at exactly 0.3048 meters by the 1959 International Yard and Pound Agreement. Squaring that value gives the modern square foot.
Historical origin. Square foot was not the invention of a single named person; it developed through the process described above.
