If a ruler shows 7 inches, how many centimeters is that?

Explanation:
Converting inches to centimeters relies on the fact that 1 inch equals 2.54 centimeters. So for 7 inches, multiply 7 by 2.54: 7 × 2.54 = 17.78 cm. That is the exact measurement in centimeters. If you round to one decimal place, it’s about 17.8 cm. The other numbers don’t reflect the precise 2.54 cm per inch.
