How to change ft to Nm?
To convert a foot measurement to a nanometer measurement, multiply the length by the conversion ratio. One foot is equal to 304,800,000 nanometers, so use this simple formula to convert:
1 ft = 304,800,000 nm
nanometers = feet × 304,800,000
The length in nanometers is equal to the feet multiplied by 304,800,000.
For example, here's how to convert 5 feet to nanometers using the formula above.
5' = (5 × 304,800,000) = 1,524,000,000 nm
