Converting between centimeters and millimeters is a frequent necessity, particularly in fields like science, engineering, and construction, where small and precise measurements are important. Both centimeters (cm) and millimeters (mm) are part of the metric system, making the conversion between them simple and straightforward. This article explains the history, uses, and conversion between centimeters and millimeters, providing a conversion table, detailed formulas, and step-by-step examples for easy understanding.
What is a Centimeter?
A centimeter is a unit of length in the metric system. One centimeter is equal to one-hundredth of a meter (1 cm = 0.01 meters) or 10 millimeters. It is widely used for everyday measurements and in scientific fields.
History of the Centimeter
The centimeter was introduced as part of the metric system in France during the late 18th century. The metric system was designed to simplify measurements by using a decimal-based structure, making it easier to convert between units. The centimeter is now one of the most commonly used units of length worldwide.
Uses of the Centimeter
- Science: Centimeters are used to measure small distances or objects, such as the length of a lab sample or the height of a plant.
- Construction and Design: Centimeters are often used in design, architecture, and furniture making to measure dimensions precisely.
- Everyday Measurements: People commonly use centimeters to measure height, clothing dimensions, or the size of objects in daily life.
What is a Millimeter?
A millimeter is a unit of length in the metric system, equal to one-thousandth of a meter (1 mm = 0.001 meters) or one-tenth of a centimeter. Millimeters are used for precise and detailed measurements.
History of the Millimeter
The millimeter is part of the metric system, which was introduced during the French Revolution. Its simplicity and ease of conversion have led to its widespread use in science, engineering, and everyday life. Millimeters provide a high level of precision for measuring very small distances.
Uses of the Millimeter
- Engineering: Millimeters are essential for precision measurements in machinery, electronics, and construction.
- Medical Applications: In the medical field, millimeters are used for measuring small anatomical distances and in imaging technologies.
- Manufacturing: Industries that require precise dimensions, such as automotive and aerospace manufacturing, use millimeters to ensure accuracy in parts and components.
Centimeters to Millimeters Conversion Table

| 5 cm | 50 mm |
| 10 cm | 100 mm |
| 20 cm | 200 mm |
| 50 cm | 500 mm |
| 100 cm | 1,000 mm |
This table provides a quick reference for converting centimeters to millimeters for commonly used values.
How to Convert Centimeters to Millimeters?
To convert centimeters to millimeters, you use the following conversion factor:
1 Centimeter = 10 MillimetersThus, the formula to convert centimeters to millimeters is:
Millimeters = Centimeters * 10Step-by-Step Conversion Example
Example 1: Convert 5 centimeters to millimeters
Step 1: Use the conversion formula:
Millimeters = 5 * 10Step 2: Calculate:
5 * 10 = 50 MillimetersTherefore, 5 centimeters is equal to 50 millimeters.
Example 2: Convert 15 centimeters to millimeters
Step 1: Use the conversion formula:
Millimeters = 15 * 10Step 2: Calculate:
15 * 10 = 150 MillimetersTherefore, 15 centimeters is equal to 150 millimeters.
