About Foot (ft)
Definition
The foot is a unit of length equal to 12 inches or exactly 0.3048 meters.
Mathematical Relationship
1 ft = 12 in = 0.3048 m = 1/3 yd = 30.48 cm.
Conversion Formula
To convert feet to meters: multiply by 0.3048. To convert meters to feet: multiply by 3.28084.
Practical Applications
Building plans, ceiling heights, personal height, pool depth, altitude in aviation, and real estate listings.
Interesting Facts
The international foot (0.3048 m exactly) differs slightly from the US survey foot (1200/3937 m), which was deprecated in 2023.
Common Mistakes
Confusing the foot with 30 cm (it's 30.48 cm). Also, forgetting that 5′10″ is not 5.10 feet — it's 5 feet 10 inches = 5.833 feet.

About Kilometer (km)
Definition
The kilometer is a unit of length equal to 1,000 meters, commonly used to express distances between geographic locations.
Mathematical Relationship
1 km = 1,000 m = 100,000 cm = 0.621371 miles. There are 1.60934 km in one mile.
Conversion Formula
To convert km to miles: multiply by 0.621371. To convert miles to km: multiply by 1.60934.
Practical Applications
Road signs, marathon distances (42.195 km), GPS navigation, geographic mapping, and aviation flight distances.
Interesting Facts
A marathon is 42.195 km. The circumference of Earth is approximately 40,075 km at the equator.
Common Mistakes
Assuming 1 km = 1 mile. A kilometer is only about 62% of a mile. Also, speed: 100 km/h ≈ 62 mph, not 100 mph.
Educational Tips
Quick approximation: multiply km by 0.6 to estimate miles, or multiply miles by 1.6 for km.
