pound force per inch to pound force per foot

Convert pound force per inch (lbf/in) to pound force per foot (lbf/ft). Use an editable surface tension converter, conversion formula, and reference table.

12

1 lbf/in = 12 lbf/ft

Calculated in your browser

Conversion formula

lbf/ft = lbf/in × 12

One pound force per inch equals 12 pound force per foot. Multiply your value in pound force per inch by this factor to get pound force per foot. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 pound force per inch:
5 × 12 = 60 lbf/ft

About these measurements

Surface tension describes force per unit length along a liquid interface.

The base reference used here is the newton per meter. One pound force per inch is 175.1268352 base units; one pound force per foot is 14.59390294 base units.

Important distinctions

Compound units must match the quantity and dimension. Temperature intervals use size factors rather than temperature offsets. Calorie and BTU entries use the explicit definitions shown.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.

Common questions

How do I convert lbf/in to lbf/ft?

Multiply the quantity in lbf/in by 12. You can also type the value into the converter above.

Can I reverse the conversion?

Yes. Use the swap button or open the pound force per foot to pound force per inch converter.
