decimal place issues... I hope.
there are ten mm in a cm
456cm == 4560mm
there are 24.5 mm per inch (it is the law).
4550mm / 25.4 = 179.527 inches
or about 14.9 feet
which is about 5 yards
which is 20% of a 'murican football field if that helps
The above comment was pointing out that each 1 centimeter is slightly less than 0.4 inches. If you want to be more precise, each centimeter is about 0.3937 inches.
