About Converting US survey feet to Nanometers
US survey foot and Nanometer both measure length. Specifically: The US survey foot is 1200/3937 meters and is retained for legacy land records, and nanometer is 1e-9 meter units.
Formula
nanometers = us survey feet × 304800609.601
This factor comes from each unit's defined relationship to the category's base unit: 1 us survey foot equals 0.304800609601 base units, and 1 nanometer equals 1e-9 base units, so dividing one by the other gives the direct us survey foot-to-nanometer factor of 304800609.601.
Simple example
1 ftUS × 304800609.6 = 304,800,609.6 nm
1 us survey foot = 304,800,609.6 nanometers.
Real-world example
10 ftUS × 304800609.6 = 3,048,006,096 nm
10 us survey feet = 3,048,006,096 nanometers.
