Formula used
One foot contains twelve inches. Torque scales by the same distance ratio. Therefore, one foot-pound equals twelve inch-pounds for direct conversion.

Torque unit guidance
Foot-pounds suit larger fastener specifications. Inch-pounds suit smaller, lower-torque assemblies. Always match the unit printed by the equipment manufacturer.
Negative torque can represent opposite rotation. Magnitude still converts using identical factors. Directional meaning depends on your engineering sign convention.
Torque and energy may share units. Their physical meanings remain completely different. Use this page only for rotational torque unit conversions.
Frequently asked questions
How many inch-pounds equal one foot-pound?
One foot-pound equals twelve inch-pounds. The conversion follows twelve inches per foot. Multiply foot-pounds by twelve to obtain inch-pounds accurately.
How do I convert inch-pounds to foot-pounds?
Divide the inch-pound value by twelve. This reverses the direct conversion factor. For example, 120 inch-pounds equals ten foot-pounds exactly.
Can this calculator convert other torque units?
Yes, it supports seven torque units. Select any available source and destination. All conversions pass through standard newton-metre factors internally.
Are negative torque values accepted?
Yes, negative values are supported. They commonly indicate the opposite rotational direction. The conversion factor does not change with direction.
Can I enter scientific notation?
Yes, entries like 2.5e3 are valid. The calculator reads common scientific notation. You may also display results using scientific notation.
Why does the exact result differ slightly?
The main result follows your rounding choice. Exact output retains more significant digits. Small differences appear when decimal conversion factors repeat.
What decimal precision should I choose?
Choose precision matching your equipment specification. Extra decimals do not guarantee extra accuracy. Manufacturer tolerances should guide every final torque setting.
Are thousands separators optional?
Yes, enable separators for easier reading. Disable them for plain numeric copying. Scientific notation ignores grouping because exponent formatting differs.
Where is calculation history stored?
History uses your browser's local storage. It never requires a database account. Clearing browser storage may remove those saved conversion rows.
Can I export the conversion history?
Yes, download history as CSV or PDF. CSV suits spreadsheets and data processing. PDF creates a compact record for sharing or printing.
Is foot-pound torque identical to foot-pound energy?
No, identical unit wording can mislead. Torque describes rotational force through distance. Energy describes work and needs different physical interpretation.
