How to Convert Kilometers to Inches
To convert a measurement in kilometers to a measurement in inches, multiply the length by the following conversion ratio: 39,370.07874 inches/kilometer.
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 length in kilometers multiplied by 39,370.07874.
For example, here's how to convert 5 kilometers to inches using the formula above.
inches = (5 km × 39,370.07874) = 196,850.393701"
How Many Inches Are in a Kilometer?
There are 39,370.07874 inches in a kilometer, which is why we use this value in the formula above.

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.[1] 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.

What Is an Inch?
An inch is a unit of length 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″.
The standard ruler is 12 inches long and is a common tool for measuring a length in inches. Another frequently used tool to perform measurements in inches is a tape measure, which commonly comes in lengths from 6' - 35'. Other types of devices used to make measurements in inches include scales, calipers, measuring wheels, micrometers, yardsticks, and even lasers.
