To convert 55 millimeter to centimeter, multiply by the conversion factor of 0.100000. So, 55 millimeter multiplied by 0.100000 equals 5.5000 centimeter.

55 millimeter equals exactly 5.500000 centimeter. For practical purposes, this is often rounded to 5.5000 centimeter.

Objects measuring approximately 55 millimeter include the diameter of a 55mm camera lens filter, the length of a compact industrial photoelectric sensor, or the diameter of a 55mm hole saw.

Converting millimeter to centimeter is useful for simplifying measurements in contexts where centimeters are the preferred unit, such as architectural drawings, textile measurements, or when dealing with larger dimensions where millimeters would result in cumbersome numbers. It aligns with international standards and professional documentation.

The easiest way to remember is to think of dividing the millimeter value by 10, or simply moving the decimal point one place to the left. For 55mm, it becomes 5.5cm. Visualizing a ruler where 10mm equals 1cm also helps solidify this relationship.
