1 meter = 100 centimeters (cm) Metric Units cm m 1 meter = 100 centimeters (cm) To convert from meters to centimeters, multiply the number of meters by 100. 2 meters equals 200 centimeters 2•100 = 200 6 meters equals 600 centimeters 6•100 = 600

1 meter = 100 centimeters (cm) Metric Units cm m 1 meter = 100 centimeters (cm) To convert from centimeters to meters, divide the number of meters by 100. 200 centimeters equals 2 meters 200÷100 = 2 600 centimeters equals 6 meters 600÷100 = 6
