How to Convert CM to MM?

1 centimeter is equal to 10 millimeters:

1 cm = 10 mm

The measurement denoted as “d,” expressed in millimeters (mm), corresponds to the measurement denoted as “d” in centimeters (cm), multiplied by a factor of 10:

d(mm) = d(cm) × 10

Examples

Example 1:

Imagine a situation where a technician must convert a length of wire from centimeters to millimeters for an accurate circuit setup. If the wire measures 25 centimeters in length, the conversion process can be performed step by step. To convert centimeters to millimeters, you can use the formula: length in millimeters = length in centimeters multiplied by 10. Therefore, 25 centimeters equals 250 millimeters.

d(mm) = 25 × 10 = 250 mm

Example 2:

Consider a scenario where a manufacturer designs a Printed Circuit Board (PCB) layout. In order to guarantee accuracy, the dimensions of components must be accurately defined. When a component’s width is specified as 6.5 centimeters, it’s important to convert it to millimeters for Printed Circuit Board (PCB) fabrication. This conversion entails multiplying the centimeter length by ten, resulting in a quantity of 65 millimeters. This meticulous conversion approach guarantees adherence to precise specifications for PCB layout that enhances the seamless functionality of electronic devices.

d(mm) = 6.5 × 10 = 65 mm

NOTE:

The metric system uses centimeters and millimeters as measurement units for length, which are the two submultiples of the base unit for length, which is the meter.
