To convert 100 centimeter to kilometer, multiply by the conversion factor 0.000010. So, 100 x 0.000010 = 0.0010 kilometer.

100 centimeter equals exactly 0.001000 kilometer. For practical purposes, this is often expressed as 0.0010 kilometer.

Objects measuring approximately 100 centimeter include a standard 100.0 centimeter meter stick, a 100.0 centimeter professional spirit level, or a 100.0 centimeter wide projector screen.

Converting centimeter to kilometer is useful for large-scale mapping, urban planning, long-distance infrastructure projects, and scientific research where small units need to be expressed in a larger, more manageable scale for clarity and consistency with international standards.

The easiest way is to remember that 100 centimeter is 1 meter. Since 1 kilometer is 1000 meters, 100 centimeter is simply 1/1000th of a kilometer, which is 0.0010 kilometer. Think of it as moving the decimal point six places to the left from centimeters to kilometers.
