It is also known as pound force/inch, lb/in, pound per inch. This unit is commonly used in the UK unit system. Pound Force Per Inch (lbf/in) has a dimension of MT-2 where M is mass, and T is time. It can be converted to the corresponding standard SI unit N/m by multiplying its value by a factor of 175.126835246.
Note that the seven base dimensions are M (Mass), L (Length), T (Time), Q (Temperature), N (Aamount of Substance), I (Electric Current), and J (Luminous Intensity).

Other units in the category of Surface tension include Dyne Per Centimeter (dyn/cm), Erg Per Square Centimeter (erg/cm2), Erg Per Square Millimeter (erg/mm2), Kilogram Force Per Meter (kgf/m), Newton Per Meter (N/m), Ounce Force Per Foot (ozf/ft), Ounce Force Per Inch (ozf/in), Pound Force Per Foot (lbf/ft), Poundal Per Foot (pdl/ft), and Poundal Per Inch (pdl/in).
