Advanced Torque Conversion Calculator
Example Data Table
| Inch-pounds | Foot-pounds | Common Use |
|---|---|---|
| 12 in-lb | 1 ft-lb | Small fastener torque |
| 60 in-lb | 5 ft-lb | Light assembly work |
| 120 in-lb | 10 ft-lb | Workshop tool setting |
| 240 in-lb | 20 ft-lb | Mechanical tightening |
| 600 in-lb | 50 ft-lb | Higher torque reference |
Formula Used
The calculator uses the fixed torque relationship between inch-pounds and foot-pounds. Since one foot equals twelve inches, one foot-pound equals twelve inch-pounds.
foot-pounds = inch-pounds ÷ 12
inch-pounds = foot-pounds × 12
The tool also supports precision control and rounding modes. This helps when a torque chart, wrench scale, or project sheet requires a specific number of decimal places.
How to Use This Calculator
Enter the torque value in the first field. Choose whether you want to convert from inch-pounds to foot-pounds or from foot-pounds to inch-pounds. Select the decimal precision and rounding method. You may also add a project label for downloaded records. Press the calculate button. The result will appear above the form and below the header. Use the CSV or PDF buttons to save the result.
Inch-Pound to Foot-Pound Conversion Guide
Why Torque Conversion Matters
Torque values appear in repair manuals, engineering sheets, product guides, and maintenance logs. Some sources list torque in inch-pounds. Others use foot-pounds. A quick conversion avoids mistakes during setup. It also helps compare readings from different tools. The relationship is simple, but accuracy still matters.
Understanding the Units
An inch-pound describes torque created by one pound of force acting at one inch from a pivot. A foot-pound uses the same idea, but the distance is one foot. Because one foot contains twelve inches, foot-pound values are smaller than inch-pound values for the same torque. This is why division by twelve is used.
Practical Workshop Use
Mechanics often convert torque before setting a wrench. A small fastener may be listed in inch-pounds. A larger wrench may show foot-pounds. This calculator helps bridge that gap. It can also reverse the calculation when a manual gives foot-pounds and a small torque driver needs inch-pounds.
Precision and Rounding
Different tasks need different precision levels. General workshop use may only need two decimals. Technical documentation may need more detail. The precision field lets you choose the final display. The rounding option lets you control how the result is prepared. Standard rounding is best for most cases.
Record Keeping
Export buttons make the calculator useful for reports. The CSV file is easy to open in spreadsheets. The PDF file is better for sharing or archiving. Add a label before calculating. This makes each saved result easier to identify later.
FAQs
1. How do I convert inch-pounds to foot-pounds?
Divide the inch-pound value by 12. For example, 120 inch-pounds equals 10 foot-pounds.
2. How do I convert foot-pounds to inch-pounds?
Multiply the foot-pound value by 12. For example, 10 foot-pounds equals 120 inch-pounds.
3. Why is the conversion factor 12?
The factor is 12 because one foot contains twelve inches. Torque changes with lever distance.
4. Can I use this for torque wrench settings?
Yes. You can convert manual values before setting a compatible torque wrench. Always follow tool limits.
5. Does rounding affect the true torque value?
Rounding only changes the displayed result. The exact value is also shown after calculation.
6. What precision should I choose?
Use two decimals for general work. Use higher precision for technical records or engineering notes.
7. Can I download the result?
Yes. Use the CSV button for spreadsheet records. Use the PDF button for printable documentation.
8. Is inch-pound the same as pound-inch?
In common torque use, both terms refer to the same unit relationship. Formatting may vary by manual.
