Calculating your newton metres (n·m) is straightforward once you know the Torque Converter formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the Torque Converter.
What is Torque Converter?
The Torque Converter calculation tells you your newton metres (n·m) from a few simple inputs. The figure you are solving for here is the newton metres (n·m).
The Torque Converter formula
This calculation combines several inputs through a multi-step method rather than a single one-line formula. Enter the values below and the calculator resolves each step in order. The inputs it needs are:
- Torque — a number. Example: 1.
- From unit — one of: Newton metres (N·m), Kilogram-force metres (kgf·m), Foot-pounds (ft·lb), Inch-pounds (in·lb). Example: Foot-pounds (ft·lb).
How to calculate it step by step
- Write down the torque (for example, 1).
- Choose the from unit (for example, Foot-pounds (ft·lb)).
- Apply the formula above to get your newton metres (n·m).
- Double-check the result with the Torque Converter.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Torque | 1 |
| From unit | Foot-pounds (ft·lb) |
| Newton metres (N·m) | 1.3558 |
| Foot-pounds (ft·lb) | 1.0000 |
| Kilogram-force metres (kgf·m) | 0.1383 |
With torque of 1 and from unit of Foot-pounds (ft·lb), the newton metres (n·m) works out to 1.3558.
Example 2
With torque of 2 and from unit of Foot-pounds (ft·lb), the newton metres (n·m) works out to 2.7116.
| Result | Value |
|---|---|
| Newton metres (N·m) | 2.7116 |
| Foot-pounds (ft·lb) | 2.0000 |
| Kilogram-force metres (kgf·m) | 0.2765 |
Example 3
With torque of 5 and from unit of Foot-pounds (ft·lb), the newton metres (n·m) works out to 6.7791.
| Result | Value |
|---|---|
| Newton metres (N·m) | 6.7791 |
| Foot-pounds (ft·lb) | 5.0000 |
| Kilogram-force metres (kgf·m) | 0.6913 |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
