About These Units
Foot (ft)
A foot (ft) is an imperial unit equal to 12 inches or 30.48 centimeters exactly. Feet measure human height, room dimensions, building heights, and elevation in the US. One foot equals 0.3048 meters. Aviation altitude is measured in feet worldwide.
Planck Length (ℓP)
The Planck length (ℓP) is approximately 1.616×10⁻³⁵ meters, the smallest meaningful length in physics where quantum gravity effects become significant. Below this scale, our current understanding of space and time breaks down. Named after physicist Max Planck.
