One foot is the unit of length, and ten inches is one foot. So 4 feet 5 inches =4.5 feet. The unit ruler is a commonly used unit of length measurement in China's clothing industry, and the unit meter is an international unit of length measurement. There is a fixed propulsion rate between them, that is, 1 m =3 feet. So 4.5 feet =4.5 divided by 3= 1.5 meters.
