How to Convert Feet to Kilometers

To convert a measurement in feet to a measurement in kilometers, multiply the length by the following conversion ratio: 0.000305 kilometers/foot.

Since one foot is equal to 0.000305 kilometers, you can use this simple formula to convert:

kilometers = feet × 0.000305

The length in kilometers is equal to the length in feet multiplied by 0.000305.

For example, here's how to convert 5,000 feet to kilometers using the formula above.
kilometers = (5,000' × 0.000305) = 1.524 km

Our inch fraction calculator can add feet and kilometers together, and it also automatically converts the results to US customary, imperial, and SI metric values.

Feet and kilometers are both units used to measure length. Keep reading to learn more about each unit of measure.

What Is a Foot?

The foot is a unit of length measurement equal to 12 inches or 1/3 of a yard. Because the international yard is legally defined to be equal to exactly 0.9144 meters, one foot is equal to 0.3048 meters.[1]

The foot is a US customary and imperial unit of length. Feet can be abbreviated as ft; for example, 1 foot can be written as 1 ft.

Feet can also be denoted using the symbol, otherwise known as a prime, though a single-quote (') is often used instead of the prime symbol for convenience. Using the prime symbol, 1 ft can be written as 1′.

Measurements in feet are most commonly taken using either a standard 12" ruler or a tape measure, though there are many other measuring devices available. Feet are sometimes referred to as linear feet, which are simply a measurement of length in feet.

What Is a Kilometer?

One kilometer is equal to 1,000 meters, which are defined as the distance light travels in a vacuum in 1/299,792,458 of a second.[2] One kilometer is equal to 0.621371 miles.

The kilometer, or kilometre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "kilo" is the prefix for thousands, or 103. Kilometers can be abbreviated as km; for example, 1 kilometer can be written as 1 km.
