How many centimeters are in 5 inches?

12.7 cm

Converting inches to centimeters uses the fact that 1 inch equals 2.54 centimeters. So for five inches, multiply: 5 × 2.54 cm = 12.7 cm. That’s why 12.7 cm is the correct amount. The other numbers come from common slip-ups: 2.54 cm is the size of one inch, not five inches; 5 cm would be if you treated the measurement as already in centimeters without multiplying; 25.4 cm would be ten inches (10 × 2.54).
