Which is the smallest measure of length: millimeter, centimerter, inches or miles
The smallest unit of length is the millimeter.
The smallest measure of length among the options given is the millimeter.
To determine the smallest measure of length among millimeter, centimeter, inches, and miles, we need to compare the magnitudes of each unit.
First, let's start with the largest unit, miles. Miles are used to measure longer distances, commonly used for measuring road distances or larger geographical measurements. Since miles are larger than inches, centimeters, and millimeters, we can eliminate miles as the smallest measure of length.
Now let's compare inches and centimeters. To make an accurate comparison, we can convert inches to centimeters so that both units are in the same measurement system (the metric system). Since there are 2.54 centimeters in an inch, we can say that 1 inch is approximately equal to 2.54 centimeters.
Finally, let's compare centimeters and millimeters. Since there are 10 millimeters in 1 centimeter, we can say that 1 centimeter is equal to 10 millimeters.
Based on these comparisons, we can conclude that the smallest measure of length is the millimeter. Millimeters are smaller than both centimeters and inches, and miles are even larger. Therefore, out of the given options, millimeters are the smallest unit of length.
