Foot and a half, or one and a half feet, is a length unit equal to 1.5 feet. It corresponds to 18 inches or 0.4572 meters (45.72 centimeters). The term arises from the common foot, a fundamental unit in the US customary and British imperial systems, and is typically used in informal or practical measurements such as construction, carpentry, and everyday sizing.

In metric terms, 1.5 feet is exactly 0.4572 meters because the foot is defined as 0.3048 meters by international agreement. Consequently, the foot and a half is a precise length in contexts where the foot’s definition is accepted; in day-to-day use, measurements are often approximated.

Conversions are straightforward. 1 foot equals 12 inches, so 1.5 feet equals 18 inches. In metric units, multiply the length in feet by 0.3048 to obtain meters, or by 30.48 to obtain centimeters. When measuring with larger fractions of a foot, decimal feet may be used for ease, but a foot and a half remains a simple and common descriptive length in many practical applications.

Contextually, the term is most often encountered in construction, furnishings, and body measurements where precise SI units are not mandatory. It is not an SI unit, and scientific contexts typically prefer meters or decimeters.
