The equivalent of 5 feet 4.5 inches in centimetres is 163.85 cm. This is the absolute value that is arrived at using a precise mathematical calculation. According to the calculation, 1 inch is equivalent to 2.54 cm. The first step would be to convert the entire number to inches. 1 foot is equivalent to 12 inches. Therefore, 5 feet would be 5 x 12, or 60 inches. Then, we add the 4.5 inches to the converted value of 5 feet, i.e. 60 inches. So, 5 feet 4.5 inches in inches would be 64.5 inches. Now we use the conversion formula for converting inches to centimetres. If 1 inch is equal to 2.54 cm, then 64.5 inches would be 64.5 x 2.54, which is 163.85 centimetres. There are some people that use the approximate conversion value between inches and centimetres, which is 2.5 cm. Though the difference here is 0.4 cm, across a larger number the difference would be significant, which has always been the problem with approximation. If you use the approximate value of 2.5 centimetres for an inch, 5 feet 4.5 inches or 64.5 inches would convert to 161.25 centimetres, which is at least 2.5 centimetres lesser than the precise value of 163.85.
