# Inch-Pounds to Ft-Lb Calculator

When working with torque measurements, it is common for people to encounter values in different units. Two of the most common units used for measuring torque are inch-pounds (in-lb) and foot-pounds (ft-lb). In certain situations, you may need to convert between these two units, and that’s where our inch-pounds to ft-lb calculator comes in handy. This calculator allows you to convert torque values between inch-pounds and foot-pounds quickly and accurately.

In this article, we will explain the formulas necessary for converting between inch-pounds and foot-pounds, as well as provide a worked example calculation to help you understand the process.

**Formulas for Conversion**

In order to convert between inch-pounds and foot-pounds, you need to understand the relationship between these two units. The conversion factor between inch-pounds and foot-pounds is based on the fact that there are 12 inches in a foot. Therefore, the relationship between the two units can be expressed as follows:

1 foot\text{--}pound (ft\text{--}lb) \\= 12 inch\text{--}pounds (in\text{--}lb)

To convert from inch-pounds to foot-pounds, you simply divide the inch-pound value by 12:

foot\text{--}pounds (ft\text{--}lb) \\= inch\text{--}pounds (in\text{--}lb) \div 12

To convert from foot-pounds to inch-pounds, you multiply the foot-pound value by 12:

inch\text{--}pounds (in\text{--}lb) \\= foot\text{--}pounds (ft\text{--}lb) * 12

Now that we have the necessary formulas, let’s go through a worked example calculation.

**Worked Example Calculation**

Let’s say you have a torque wrench that is calibrated in inch-pounds, and you need to apply a torque of 90 ft-lb to a bolt. To do this, you will need to convert the ft-lb value to in-lb.

Using the formula to convert from foot-pounds to inch-pounds, we can calculate the equivalent inch-pound value:

inch\text{--}pounds (in\text{--}lb) \\= foot\text{--}pounds (ft\text{--}lb) * 12

inch\text{--}pounds (in\text{--}lb) \\= 90 ~ft\text{--}lb * 12

inch\text{--}pounds (in\text{--}lb) = 1080 ~in\text{--}lb

So, in order to apply a torque of 90 ft-lb, you would need to set your torque wrench to 1080 in-lb.

Now, let’s say you’ve used the torque wrench and want to convert the torque value back to ft-lb to make a note of it. Using the formula to convert from inch-pounds to foot-pounds, we can calculate the ft-lb value:

foot\text{--}pounds (ft\text{--}lb) \\= Inch\text{--}pounds (in\text{--}lb) \div 12

foot\text{--}pounds (ft\text{--}lb) \\= 1080 ~in\text{--}lb \div 12

foot\text{--}pounds (ft\text{--}lb) = 90 ~ft\text{--}lb

As expected, the conversion back to ft-lb gives us the original value of 90 ft-lb.

**Using the Inch-Pounds to Ft-Lb Calculator**

While it is important to understand the formulas and calculations involved in converting between inch-pounds and foot-pounds, using our inch-pounds to ft-lb calculator makes the process much simpler and faster. To use the calculator, follow these steps:

Step | Step Description |
---|---|

1 | Input the torque value you want to convert in the appropriate unit field (either inch-pounds or foot-pounds). |

2 | Click the “Convert” button. |

3 | The calculator will display the equivalent torque value in the other unit. |

For example, if you input 1080 in-lb and click the “Convert” button, the calculator will display 90 ft-lb as the equivalent torque value.

**Conclusion**

Understanding how to convert between inch-pounds and foot-pounds is important when working with torque measurements in various applications. Our inch-pounds to ft-lb calculator makes it easy to convert between these two units quickly and accurately. With the formulas and worked example provided in this article, you should have a solid grasp of the conversion process and be well-equipped to use our calculator to make your torque conversions a breeze.
