  2. Substitute the required value. In this case we substitute 5000 for ft so the formula becomes: km = 5000 ÷ 3281
  3. Calculate the result using the provided values. In our example the result is: 5000 ÷ 3281 = 1.5239256324291374580920451082 km

In summary, 5000 feet is equal to 1.5239256324291374580920451082 kilometers.

Converting kilometers to feet

Converting kilometers to feet involves a simple multiplication since both are units of length, but they are of different magnitudes. Here's how you can convert kilometers to feet. 1 kilometer (km) is equal to 3,280.84 feet (ft) So, to convert kilometers to feet, you can use the following formula: ft = km × 3280.84Using these conversion factors, you can convert kilometers to feet step by step. The step-by-step process is shown below.

1. Convert Kilometers to Meters

Multiply the number of kilometers by 1000 to convert them to meters. For example, if you have 5 kilometers: 5 km × 1000 m/km = 5000 m.

2. Convert Meters to Feet

Multiply the number of meters by 3.28084 to convert them to feet. Using the 5000 meters from the previous step: 5000 m × 3.28084 ft/m ≈ 16404.2 ft.

So, 5 kilometers is approximately equal to 16404.2 feet. Alternatively, if you want a shortcut, you can combine the conversion factors directly: Feet = Kilometers × 1000 × 3.28084.

Conversion Unit Definitions

What is a Foot?

The foot (pl. feet), standard symbol: ft, is a unit of length in the British imperial and United States customary systems of measurement. The prime symbol, ′, is a customarily used alternative symbol. Since the International Yard and Pound Agreement of 1959, one foot is defined as 0.3048 meters exactly. In both customary and imperial units, one foot comprises 12 inches and one yard comprises three feet.
Historically the "foot" was a part of many local systems of units, including the Greek, Roman, Chinese, French, and English systems. It varied in length from country to country, from city to city, and sometimes from trade to trade. Its length was usually between 250 mm and 335 mm and was generally, but not always, subdivided into 12 inches or 16 digits.
The United States is the only industrialized nation that uses the international foot in preference to the meter in its commercial, engineering, and standards activities. The foot is legally recognized in the United Kingdom; road signs must use imperial units (however, distances on road signs are always marked in miles or yards, not feet), while its usage is widespread among the British public as a measurement of height.
Here are some more details about the foot:
  1. Historical Context: The foot has been used as a unit of measurement for thousands of years and has roots in various ancient civilizations. It was originally based on the length of a human foot, but over time, standardized units were developed to ensure consistency.

  2. Imperial and US Customary Systems: The foot is a fundamental unit in both the Imperial system and the United States Customary system. These systems of measurement are closely related and share many common units. The foot is divided into 12 inches and is further subdivided into smaller units such as the inch, half-inch, quarter-inch, etc.

  3. Length Conversion: As mentioned earlier, one foot is equal to 12 inches or approximately 30.48 centimeters. Conversely, one inch is equal to 1/12th of a foot.

  4. Symbol: The symbol for foot is a single prime ('). For example, a measurement of 5 feet would be written as 5'.

  5. Usage: The foot is commonly used in various applications, including construction, architecture, interior design, surveying, and sports. It is often used to measure heights, distances, room dimensions, and other similar quantities.

  6. Subdivisions: The foot can be divided into smaller units to measure finer lengths. Apart from the inch, mentioned earlier, there are also other subdivisions used in specific contexts. For example, in surveying, a foot can be divided into tenths or hundredths for precise measurements.

  7. International Usage: While the metric system (based on the meter) is the predominant system of measurement used worldwide, the foot is still used in certain countries, such as the United States and the United Kingdom, especially in everyday contexts. However, it's worth noting that in scientific, technical, and international contexts, the meter is typically used for consistency and compatibility.
