How to Convert Kilometers to Inches

To convert a kilometer measurement to an inch measurement, multiply the length by the conversion ratio.

Since one kilometer is equal to 39,370.07874 inches, you can use this simple formula to convert:

inches = kilometers × 39,370.07874

The length in inches is equal to the kilometers multiplied by 39,370.07874.

For example, here's how to convert 5 kilometers to inches using the formula above.
5 km = (5 × 39,370.07874) = 196,850.393701"

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

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


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.[1]

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.


An inch is a unit of linear length measure equal to 1/12 of a foot or 1/36 of a yard. Because the international yard is legally defined to be equal to exactly 0.9144 meters, one inch is equal to 2.54 centimeters.[2]

The inch is a US customary and imperial unit of length. Inches can be abbreviated as in; for example, 1 inch can be written as 1 in.

Inches can also be denoted using the symbol, otherwise known as a double-prime. Often a double-quote (") is used instead of a double-prime for convenience. A double-prime is commonly used to express 1 in as 1″.

A quarter is .955" in diameter, which is just smaller than 1"

The standard ruler has 12", and is a common measuring tool for measuring inches. They are also often measured using tape measures, which commonly come in lengths from 6' - 35'. Other types of measuring devices include scales, calipers, measuring wheels, micrometers, yardsticks, and even lasers.

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.
