Foot (ft). The foot equals exactly 0.3048 meters, or 12 inches, and is widely used for height and room sizes in India, the US and the UK.
Fermi (fm). A fermi (femtometer) is 10⁻¹⁵ meters, roughly the size of a proton, used in nuclear physics.
There are 304,800,000,000,000 fermis in one foot.
Multiply the number of feet by 304,800,000,000,000. For example, 10 feet equal 3.048 × 10¹⁵ fermis.
One fermi equals 3.28084 × 10⁻¹⁵ feet.
3.6576 × 10¹⁵ fermis. Other common values: 5 feet = 1.524 × 10¹⁵ fermis and 100 feet = 3.048 × 10¹⁶ fermis.
