1 foot = 304,800,000 nanometers – The nanometer is so small that millions of them fit into a single foot

To convert a length from feet to nanometers, multiply the number of feet by 304,800,000:

Nanometers = Feet × 304,800,000

This is because 1 foot equals exactly 304,800,000 nanometers.

Convert 2.5 feet to nanometers:

Nanometers = 2.5 × 304,800,000 = 762,000,000 nm

A foot (symbol: ft) is a unit of length in the imperial and US customary systems of measurement. It is defined as exactly 0.3048 meters.

A nanometer (symbol: nm) is a unit of length in the metric system, equal to one billionth of a meter (1 × 10^-9 m).

Feet (ft)	Nanometers (nm)	Scientific Notation

Human Hair: A human hair is approximately 80,000-100,000 nanometers in diameter, which is about 0.0003 feet.
Red Blood Cell: A red blood cell is about 7,000-8,000 nanometers in diameter, which is about 0.000026 feet.
Visible Light: The wavelength of visible light ranges from about 400-700 nanometers, which is an incredibly small fraction of a foot.
Semiconductor Chip Features: Modern semiconductor chip features can be as small as 5-10 nanometers, showing the extreme precision of modern manufacturing.
DNA Double Helix: The width of a DNA double helix is about 2.5 nanometers, or about 0.000000008 feet.

These comparisons highlight the vast difference in scale between feet and nanometers, with 1 foot containing 304,800,000 nanometers.
