How many centimeters are in 60 millimeters?

• A. 6 cm
• B. 0.6 cm
• C. 60 cm
• D. 600 cm

Answer: (A)

Converting millimeters to centimeters uses the relationship that 1 centimeter equals 10 millimeters. To change millimeters to centimeters, divide by 10. So for 60 millimeters, 60 ÷ 10 = 6, which is 6 centimeters. The correct choice is the one that states 6 cm. The other numbers would correspond to different lengths: 0.6 cm would be 6 mm, 60 cm would be 600 mm, and 600 cm would be 6000 mm.
