Measurement Systems

Imperial System (Feet)

Used in United States, aviation, and older topographic maps. 1 foot = 12 inches.

Metric System (Meters)

International standard, used in science, most countries, and modern mapping. 1 meter = 100 cm.

Conversion Factor

1 foot = 0.3048 meters exactly. This definition was adopted internationally in 1959.

Altitude Formulas

Pressure Altitude Formula

Altitude (ft) = (1 - (P/P₀)^(1/5.25588)) × 145366.45

Where P is current pressure, P₀ is sea level pressure (29.92 inHg)

Oxygen Availability

O₂% = 0.21 × (P/P₀) × 100

Percentage of sea level oxygen available at altitude

Feet to Meters

meters = feet × 0.3048

Exact conversion factor established in 1959

Historical Facts

The foot was originally based on the average length of a human foot. The current international foot (0.3048 m) was adopted in 1959.

The meter was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole.

Mount Everest's height was first accurately measured in 1856 as 29,002 ft. Modern measurements show 29,031.7 ft (8,848.86 m).
