To convert feet to kilometers, use this formula:
Kilometers = Feet × 0.0003048
For example, to convert 10,000 feet to kilometers:
10,000 × 0.0003048 = 3.048 km
This means that 1 foot equals 0.0003048 kilometers, and 1 kilometer equals 3,280.84 feet.

The Story of Aviation: From Feet to Kilometers
The aviation industry relies on both feet and kilometers for navigation and altitude measurements. While altitudes are measured in feet, flight distances between cities are usually given in kilometers.
One famous example is Charles Lindbergh's transatlantic flight in 1927, where he flew from New York to Paris in 33.5 hours, covering 3,600 miles (approximately 5,794 km). His altitude was measured in feet, but his journey was recorded in kilometers—highlighting how both measurement systems coexist in global travel.
