## Step-by-Step Conversion Process

To convert centimeters to millimeters, follow these simple steps:

**Identify the original measurement:**Start with the measurement you have, which in this case is 7.7 cm.**Understand the conversion factor:**Know that 1 centimeter equals 10 millimeters.**Apply the conversion formula:**Multiply the number of centimeters (7.7 cm) by the conversion factor (10).**Result:**7.7 cm × 10 mm/cm = 77 mm.

This formula can be used generally to convert any value in centimeters to millimeters. Thus, if you need to convert centimeters to millimeters, simply multiply by 10.
