Linear Foot (L.F.)
Linear foot measurements are found in the component boxes and in the schedules of expenditures. Due to our Canadian construction background we have a bias towards the imperial system – although we work in metric readily. Simply put, lineal refers to ancestry and is not to be confused with linear. In some fields, ‘lineal’ describes a quantity of material that has an implied width dimension, and ‘linear’ describes a distance regardless of width. Consider the replacement of metal panel cladding, and a building having 20 linear foot to an eave, such that 20 lineal foot of metal would be required. There exists a factor to convert lineal foot to square foot – defined by the width of the material specified – but such a concept does not readily apply to measurements and industries that use the term ‘linear’.
