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.
Planck length (ℓP). The Planck length is about 1.616 × 10⁻³⁵ meters, the smallest length that has meaning in current physics theories.
There are 1.88584 × 10³⁴ Planck lengths in one foot.
Multiply the number of feet by 1.88584 × 10³⁴. For example, 10 feet equal 1.88584 × 10³⁵ Planck lengths.
One Planck length equals 5.30267 × 10⁻³⁵ feet.
2.26301 × 10³⁵ Planck lengths. Other common values: 5 feet = 9.42921 × 10³⁴ Planck lengths and 100 feet = 1.88584 × 10³⁶ Planck lengths.
