Ft-Lb Calculator
Torque is a critical measurement in mechanics, engineering, automotive work, and physics. Whether you are tightening bolts, designing machinery, or studying rotational force, accurate torque calculation is essential. Our Ft-Lb Calculator helps you quickly determine torque using force and distance, without manual formulas or unit confusion.
This calculator not only gives results in foot-pounds (ft-lbs) but also converts them into inch-pounds (in-lbs) and newton-meters (N·m) for international and technical use.
An Ft-Lb Calculator is a torque calculation tool that multiplies applied force by distance to determine rotational force. Torque is commonly measured in foot-pounds (ft-lbs) and is widely used in mechanical, automotive, and engineering fields.
The calculator simplifies the process by automatically converting values into multiple torque units.
What Is Torque? (Simple Explanation)
Torque is the force that causes an object to rotate around an axis.
Formula:
Torque = Force × Distance
- Force is measured in pounds
- Distance is measured in feet
- Result is torque in foot-pounds
This calculator performs this calculation instantly and accurately.
Why Use an Ft-Lb Calculator?
Using a calculator instead of manual math helps you:
- Avoid calculation errors
- Save time
- Convert units automatically
- Improve accuracy in mechanical work
- Understand torque relationships easily
It is especially useful when precision matters, such as bolt tightening or equipment setup.
How to Use the Ft-Lb Calculator (Step-by-Step)
Using the calculator is very easy:
Step 1: Enter Force
Input the applied force in pounds.
Step 2: Enter Distance
Enter the distance from the pivot point in feet.
Step 3: Click “Calculate”
The calculator instantly shows:
- Torque in ft-lbs
- Torque in in-lbs
- Torque in N·m
Example Calculation
Let’s understand with a simple example:
- Force: 25 pounds
- Distance: 2 feet
Results:
- Torque: 50 ft-lbs
- Inch-Pounds: 600 in-lbs
- Newton-Meters: 67.79 N·m
This example shows how increasing distance or force increases torque.
