A foot (plural: feet) is a unit of length in the imperial and U.S. customary systems, equal to 12 inches or 0.3048 meters. It's abbreviated as ft and is commonly used in the United States for measuring height, depth, length, and distance in both everyday and professional settings.
The foot provides a practical middle ground between inches and yards, making it useful for measuring spaces, human height, and furniture dimensions. Its consistent use in housing, sports, and aviation has made it one of the most recognizable non-metric units worldwide.
Uses: Feet are widely used in the U.S. and other countries that follow the imperial system. In construction and real estate, feet are used to describe room dimensions, ceiling heights, and lot sizes. In aviation, altitude is measured in feet. Sports fields, such as basketball and football courts, are also defined using feet.
In daily life, people often use feet to describe height ("I’m 5 feet 10 inches tall") or to estimate walking distances. Architects, builders, and interior designers frequently rely on feet for sketches and plans. Whether you're measuring a wall or flying at 30,000 feet, this unit remains a practical and familiar part of daily measurements.
A kilometer is a unit of length in the metric system equal to 1,000 meters. Abbreviated as km, it's commonly used to measure longer distances that go beyond the range of everyday indoor measurements. One kilometer is approximately 0.621 miles.
Because it's a large unit, the kilometer is ideal for expressing distances in transportation, travel, and geography. It offers a convenient way to describe how far apart places are without resorting to large numbers in meters. Whether on a road sign or a GPS app, the kilometer is a familiar standard for navigating space
Uses: Kilometers are widely used in most countries that follow the metric system. In transportation, they measure the length of roads, the distance between cities, and vehicle speed in kilometers per hour (km/h). In athletics, races like 5K or 10K runs are named using kilometers to define the course length.
Kilometers also play a role in mapping and land surveying, helping define property lines, elevations, and geographic boundaries. For outdoor activities like hiking, biking, or road trips, kilometers provide an easy way to track and communicate distance. It's a unit that supports both everyday travel and large-scale navigation.
1 Feet = 0.000305 Kilometer
Let’s say you want to convert 100 Feet to Kilometer.
Using the formula:
100 × 0.000305 = 0.03 Kilometer
So, 100 Feet is approximately 0.03 Kilometer.
