Centimeters to Inches Converter

Converting Centimeters to Inches

Changing measurements from metric (centimeters) to imperial (inches) is frequently required for screen sizes, clothing measurements, and small object dimensions.

Conversion Rate

One inch is exactly defined as 2.54 centimeters. Therefore, the conversion logic represents this ratio.

Formula: Inches = Centimeters / 2.54

Visualizing the Difference

Imagine a standard ruler. A 12-inch ruler is about 30 centimeters long. This gives you a rough idea: 30cm ≈ 1 foot. If you look closer, you'll see that 1 cm is much smaller than an inch—less than half the width.

Quick Reference Chart

• 1 cm = 0.39 inches
• 5 cm = 1.97 inches
• 10 cm = 3.94 inches
• 20 cm = 7.87 inches
• 25 cm = 9.84 inches
• 50 cm = 19.69 inches
• 100 cm = 39.37 inches

Real World Examples

Rulers: Most school rulers show 30 cm which is approximately 12 inches (1 foot).

Screen Sizes: TVs and monitors are measured diagonally in inches, but the device dimensions might be listed in cm. A 55-inch TV has a diagonal of roughly 140 cm.

Clothing: Waist sizes are often in inches, but international sizing charts provide cm. A 32-inch waist is about 81 cm.

Accuracy Tip

For rough estimates, you can assume that 2.5 cm is 1 inch. However, for precise engineering or fitting, always use 2.54 as the divisor or use our calculator for exact results.
