Lbs/ft to Lbs/in Formula
The following formulas convert pounds per foot to pounds per inch and back.
\mathrm{lb/in} = \tfrac{1}{12}\,\mathrm{lb/ft}- 1 ft = 12 in
- 1 ft = 0.3048 m; 1 in = 2.54 cm
- 1 lb = 0.45359237 kg
- 1 oz = 28.349523125 g

| * Relation: lb/in = lb/ft ÷ 12 (since 1 ft = 12 in). | |
How do you convert lb/ft to lb/in? Divide by 12 because there are 12 inches in a foot: lb/in = lb/ft ÷ 12.
How do you convert lb/in to lb/ft? Multiply by 12: lb/ft = lb/in × 12; for metric, convert through kg/m and cm/in as needed.
Example Problem
Convert 2.4 lb/ft to lb/in.
Use the formula: lb/in = lb/ft ÷ 12.
lb/in = 2.4 ÷ 12 = 0.2 lb/in
