To determine which unit of measurement is longest or farthest, we need to compare the values of millimeters, centimeters, meters, and kilometers.

First, let's start with the basic unit of measurement, which is the meter. A meter can be thought of as a standard unit of length.

Now, let's consider millimeters (mm). The prefix "milli" indicates that it is one thousandth of a meter, which means there are 1,000 millimeters (mm) in a meter. Therefore, millimeters are smaller than meters.

Next, we have centimeters (cm). The prefix "centi" indicates that it is one hundredth of a meter, which means there are 100 centimeters (cm) in a meter. So, centimeters are also smaller than meters but larger than millimeters.

Moving on, we have kilometers (km). The prefix "kilo" indicates that it is one thousand meters. Therefore, there are 1,000 meters in a kilometer. Kilometers are much larger than meters, centimeters, and millimeters.

So, to compare the four units in terms of length or distance, the order is as follows (from smallest to largest):

millimeters (mm) < centimeters (cm) < meters (m) < kilometers (km)

In conclusion, kilometers are the longest or farthest unit of measurement among millimeters, centimeters, meters, and kilometers.
