What is a Torque Converter?
A Torque Converter is a free online tool that converts torque measurements between newton-metres (Nm), foot-pounds (ft-lb), and inch-pounds (in-lb). It is essential for automotive work, engineering, and mechanical applications where torque specifications vary by region.
How to calculate torque conversion manually (the formula)
Torque conversion uses fixed conversion factors. To convert Nm to ft-lb, divide by 1.35582. To convert ft-lb to Nm, multiply by 1.35582. To convert ft-lb to in-lb, multiply by 12. To convert in-lb to ft-lb, divide by 12.
Example calculation
Convert 100 Nm to ft-lb: 100 ÷ 1.35582 = 73.756 ft-lb. Convert 50 ft-lb to Nm: 50 × 1.35582 = 67.791 Nm. Convert 10 ft-lb to in-lb: 10 × 12 = 120 in-lb.
Common mistakes
- Confusing Nm with ft-lb — One Nm is approximately 0.738 ft-lb. They are close but different; using them interchangeably can damage components.
- Forgetting the inch-to-foot conversion — There are 12 inch-pounds in one foot-pound, not 10.
- Using wrong conversion direction — Multiplying instead of dividing (or vice versa) is a common error. Check if the target unit is larger or smaller.
Frequently asked questions
What is a Torque Converter?
A Torque Converter is a tool that converts torque measurements between units such as newton-metres, foot-pounds, and inch-pounds.
How do I convert Nm to ft-lb?
To convert newton-metres to foot-pounds, divide the torque in Nm by 1.35582. For example, 100 Nm ÷ 1.35582 = 73.756 ft-lb.
What is the formula for converting ft-lb to Nm?
To convert foot-pounds to newton-metres, multiply the torque in ft-lb by 1.35582. For example, 50 ft-lb × 1.35582 = 67.791 Nm.
How many inch-pounds are in one foot-pound?
There are 12 inch-pounds in one foot-pound. To convert ft-lb to in-lb, multiply by 12.
What is torque measured in?
Torque is measured in units of force times distance. Common units include newton-metres (Nm), foot-pounds (ft-lb), and inch-pounds (in-lb).
