Example Data Table
| Foot-Pounds | Formula | Inch-Pounds |
|---|---|---|
| 1 ft-lb | 1 × 12 | 12 in-lb |
| 5 ft-lb | 5 × 12 | 60 in-lb |
| 10 ft-lb | 10 × 12 | 120 in-lb |
| 25 ft-lb | 25 × 12 | 300 in-lb |

Formula Used
The standard conversion is simple because one foot equals twelve inches.
Inch-pounds = foot-pounds × 12
With advanced settings, this calculator uses the following expanded formula:
Inch-pounds = (foot-pounds × multiplier × 12) + offset
The tolerance range is calculated by subtracting and adding the selected percentage from the final inch-pound result.
How to Use This Calculator
- Enter your torque value in foot-pounds.
- Keep the multiplier at 1 for standard conversion.
- Add an offset only when your procedure requires it.
- Select decimal precision and rounding style.
- Add tolerance if you need a low and high range.
- Enter batch values when converting many torque settings.
- Press Calculate to show results above the form.
- Use CSV or PDF buttons to save the output.
Torque Conversion Guide
Foot-pound and inch-pound units describe rotational force. They are common in automotive, mechanical, bicycle, and workshop tasks. A foot-pound uses a one foot lever arm. An inch-pound uses a one inch lever arm. Because one foot equals twelve inches, the conversion is simple and reliable. The inch-pound result is always twelve times the foot-pound input.
Why Accurate Torque Matters
Correct torque protects parts from damage. Low torque can let a fastener loosen. Excess torque can stretch bolts, crush gaskets, or strip threads. Many tools display only one torque unit. This calculator helps you move between units before setting a wrench. It also keeps a clear record for inspections, repairs, and repeat work.
Advanced Calculator Features
The form accepts a main foot-pound value and optional batch values. You can apply a multiplier for calibration, coating factors, or safety checks. You can add a direct inch-pound offset when a procedure requires an extra allowance. Decimal precision and rounding style are adjustable. The tolerance field creates a low and high range. That range is useful when a manual gives an acceptable torque band.
Reading the Results
The primary result shows inch-pounds. The tool also displays a checked foot-pound value, a Newton meter estimate, and tolerance limits. The batch table converts several values at once. You can download the calculation as a CSV file. You can also export a simple PDF report for job notes or client records.
Best Use Cases
Use the converter when manuals list foot-pounds but your torque wrench uses inch-pounds. It is also helpful for small engines, assemblies, appliance repairs, and lightweight machinery. Store the exported report with service notes. This creates a repeatable process and reduces mistakes. Always confirm the required torque from the manufacturer. Lubrication, fastener grade, thread condition, and material strength can change the correct setting.
Practical Tips
Enter values from the service chart, not estimates. Clean the fastener first. Select a rounding level that matches your wrench scale. Recheck converted numbers before tightening critical parts. For assemblies with several bolts, follow the correct sequence. Record final settings, date, tool name, and technician notes for easier future maintenance. This improves consistency across repeated jobs.
FAQs
What is one foot-pound in inch-pounds?
One foot-pound equals twelve inch-pounds. Multiply the foot-pound value by 12 to get the inch-pound value.
What formula does this calculator use?
The basic formula is inch-pounds = foot-pounds × 12. Advanced settings can also apply a multiplier and an inch-pound offset.
Can I convert many values at once?
Yes. Add multiple foot-pound values in the batch box. Separate each value with commas, spaces, or semicolons.
Why is torque conversion important?
Torque conversion helps match service manuals, tool scales, and inspection records. It reduces mistakes when tools use different units.
What does the multiplier field do?
The multiplier adjusts the entered torque before conversion. Use 1 for normal work. Use another value for calibration or special factors.
What does the offset field do?
The offset adds a direct inch-pound amount after conversion. Leave it at zero unless your procedure requires an extra allowance.
Does rounding change the true value?
Rounding changes only the displayed result. The actual conversion still follows the selected formula and entered values.
Can I save the calculation?
Yes. After calculating, use the CSV button for spreadsheet data or the PDF button for a simple printable report.
