How to Convert LBF*IN to LBF*FT (Pound-force inch to Pound-force foot)?
We can convert pound-force inch to pound-force foot by using an example.
Example:
Convert 20 Pound-force inch to Pound-force foot?
We know 1 Pound-force inch = 0.0833333 pound-force foot; 1 Pound-force foot = 12.0000027 pound-force inch.
20 pound-force inch = ___lbf*ft
20 × 0.0833333 = 1.66667 lbf*ft (we know 1 pound-force inch = 0.0833333 pound-force foot)
Answer:
20 pound-force inch = 1.66667 pound-force foot
Pound-Force Inches to Pound-Force Feet: Scaling Up Imperial Torque
Converting lbf·in to lbf·ft is the reverse of the ft-to-in conversion: divide by 12 since 12 inches make 1 foot. This is needed when a small-scale specification needs to be compared against ft·lb torque wrench settings, or when crossing the threshold between inch-pound and foot-pound tool ranges.
- Take the torque in lbf·in.
- Divide by 12.
- The result is the torque in lbf·ft.
- Example: 96 lbf·in ÷ 12 = 8 lbf·ft.
lbf·in to lbf·ft Conversion Table
Inch-pound values converted to foot-pounds for torque wrench selection:
| Pound-force inch | Pound-force foot |
|---|---|
| 12 lbf·in | 1 lbf·ft |
| 24 lbf·in | 2 lbf·ft |
| 48 lbf·in | 4 lbf·ft |
| 72 lbf·in | 6 lbf·ft |
| 96 lbf·in | 8 lbf·ft |
| 120 lbf·in | 10 lbf·ft |
| 180 lbf·in | 15 lbf·ft |
| 240 lbf·in | 20 lbf·ft |
Solved Examples: lbf·in to lbf·ft
Question 1: A manual specifies 144 lbf·in for a thermostat bolt. What is this in lbf·ft?
Solution:
lbf·ft = lbf·in ÷ 12
= 144 ÷ 12
= 12 lbf·ft
Answer: 144 lbf·in = 12 lbf·ft — right at the low end of a typical ft·lb torque wrench.
Question 2: A TPMS sensor requires 62 lbf·in. Express in lbf·ft for your torque wrench.
Solution:
lbf·ft = lbf·in ÷ 12
= 62 ÷ 12
= 5.17 lbf·ft
Answer: 62 lbf·in = 5.17 lbf·ft — too low for most ft·lb wrenches, use an in·lb wrench.
Question 3: An exhaust manifold stud spec is 204 lbf·in. Convert to lbf·ft.
Solution:
lbf·ft = lbf·in ÷ 12
= 204 ÷ 12
= 17 lbf·ft
Answer: 204 lbf·in = 17 lbf·ft — comfortably in the ft·lb wrench range.

Try solving these on your own to test your understanding:
- Convert 36 lbf·in to lbf·ft. (Answer: 3 lbf·ft)
- A bolt needs 156 lbf·in. Express in lbf·ft. (Answer: 13 lbf·ft)
- Convert 84 lbf·in to lbf·ft. (Answer: 7 lbf·ft)
- A spec says 200 lbf·in. What is this in lbf·ft? (Answer: 16.67 lbf·ft)
- Convert 300 lbf·in to lbf·ft. (Answer: 25 lbf·ft)
The 120 lbf·in Crossover Point
Most mechanics consider 120 lbf·in (10 lbf·ft) the practical crossover point between in·lb and ft·lb torque wrenches. Below 120 lbf·in, use a 1/4" drive inch-pound wrench for accuracy. Above 120 lbf·in (10 lbf·ft), switch to a 3/8" drive ft·lb wrench. Both tools are available at this range, but each is most accurate in its primary range (middle 80% of scale).
Avoiding Unit Confusion on Service Manuals
Some older American service manuals abbreviate "inch-pounds" as "in-lbs" or even just "lbs" with a footnote. Always check whether a torque spec is in in·lb or ft·lb before tightening. A 25 ft·lb spec misread as 25 in·lb (only 2.08 ft·lb) would leave the fastener dangerously loose. Similarly, 25 in·lb misread as ft·lb would overtighten by 12× and likely break the component.
Key Takeaways
- 1 lbf·in = 0.08333 lbf·ft (divide by 12).
- 12 lbf·in = 1 lbf·ft exactly.
- Below 120 lbf·in (10 lbf·ft): use an inch-pound torque wrench.
- Above 120 lbf·in: switch to a foot-pound torque wrench.
- Always verify whether a spec is in·lb or ft·lb to avoid 12× errors.
