If 5 inches are converted to centimeters, which is closest?

Explanation:
Converting inches to centimeters is the idea here. Use the standard conversion: 1 inch equals 2.54 centimeters. Multiply the inches by 2.54: 5 × 2.54 = 12.7. So 5 inches is 12.7 centimeters. That value is the closest to the real conversion, since it’s exact. For intuition, 10.0 cm is about 3.94 inches, while 14.0 cm is about 5.51 inches and 15.0 cm is about 5.91 inches, all noticeably farther from 5 inches.
