How to Use the Ft Lbs Calculator
- Enter a value in the “Enter Value” field (e.g.,
100). Supports decimals. - Select the unit you’re converting from in the “From” dropdown (e.g., Foot-pound).
- Select the unit you want to convert to in the “To” dropdown (e.g., Newton-meter).
- Click “Convert” (or press Enter). The result appears below in bold green.
What it does: Converts torque values between foot-pounds (ft·lb), newton-meters (Nm), inch-pounds (in·lb), and kilogram-force meters (kgf·m).
Tip: If you choose the same unit for “From” and “To”, the value remains unchanged. The formula shows the conversion steps for clarity.

Frequently Asked Questions
A foot-pound is a unit of torque representing the rotational force applied by one pound-force acting at a radius of one foot.
Multiply ft·lb by 1.3558179483314004 to get Nm.
Torque is a measure of rotational force, while energy (like foot-pound force) is work done. They share units but are conceptually different.
