Convert 18 inches to centimeters?

• A. 7.1 cm
• B. 12.6 cm
• C. 32.0 cm
• D. 45.7 cm

Answer: (D)

To convert inches to centimeters, use the fact that 1 inch equals 2.54 centimeters. Multiply the inches by 2.54: 18 × 2.54 = 45.72 centimeters. Depending on the required precision, this rounds to 45.7 cm if you’re reporting one decimal place, which is a common level of rounding in practice. So 18 inches is about 45.7 cm. The other numbers don’t align with the conversion factor; they fall well short or exceed what 18 inches should be in centimeters (e.g., 7.1 cm, 12.6 cm, and 32.0 cm).
