The metric system is an international system of units that is used extensively in the sciences. The most common unit of length in the metric system is the meter (m), which is equal to around 3.3 feet or 1.1 yards. One meter is equal to 1,000 millimeters (mm), so to convert from meters to millimeters, one simply multiplies by 1,000.

For example, 3 meters would be 3,000 millimeters.
To convert a length in inches to millimeters, one must first convert inches to centimeters. There are 2.54 centimeters in an inch, so to convert from inches to centimeters, one multiplies by 2.54.

For example, 12 inches would be 12 x 2.54 = 30.48 centimeters. To convert from centimeters to millimeters, one simply multiplies by 10. Therefore, 30.48 centimeters would be 30.48 x 10 = 304.8 millimeters.

Now that we know how to convert from inches to millimeters, we can answer the original question of how many millimeters are in 1 3/8 inches. 1 3/8 inches is equal to 1.375 inches. To convert from inches to centimeters, we multiply by 2.54, so 1.375 inches is equal to 1.375 x 2.54 = 3.175 centimeters.
