## How to Convert Feet to Kilometers To convert a foot measurement to a kilometer measurement, multiply the length by the conversion ratio. One foot is equal to 0.000305 kilometers, so use this simple formula to convert:

kilometers = feet × 0.000305

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

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

The foot is a unit of linear length measure 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.

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

The foot is most commonly measured 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 is simply the value of a length in feet, learn more.

## Kilometers

One kilometer is equal to 1,000 meters, which are defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.

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 103. Kilometers can be abbreviated as km, for example 1 kilometer can be written as 1 km.

We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or combination with both values, so make sure you get the correct type for your needs.

If you need a ruler you can also download and print our free printable rulers, which include both imperial and metric measurements.
