Torque Conversion Calculator
This torque conversion calculator turns any moment-of-force value into every other torque unit at once, so you can move between Newton-meters, foot-pounds, inch-pounds and kilogram-force units without doing the math by hand. Type one number and the full table updates instantly.
It is built for automotive technicians matching bolt specs across metric and imperial, mechanical engineers, DIY mechanics following service manuals from any country, RC hobbyists comparing servo ratings in kgf·cm and oz·in, and students learning about rotational force. Sixteen units are supported across metric and imperial groups, from kilonewton-meters down to dyne-centimeters.
How to Convert Torque Units
Enter a value
Type your torque amount in the input field. Large numbers are automatically grouped with thousand separators so they stay easy to read.
Choose your source unit
Open the unit dropdown and pick the unit you are converting from. Start typing a name or symbol, like foot or nm, to filter the list quickly.
Read every conversion
Results appear instantly below in all enabled units, grouped into Metric and Imperial. Use Decimals to show 2, 4, 6 or 8 places, or Auto.
Copy what you need
Click a result's copy button to grab one value, or use Copy All Results to copy every conversion at once for work orders and specs.
Features
Instant Conversion
Every unit recalculates in real time as you type. There is no convert button and no waiting for results.
Smart Input Formatting
Large numbers are grouped with thousand separators so you can read and verify your input at a glance.
Searchable Unit Selection
Filter the dropdown by typing a unit name or symbol to jump straight to the one you need.
Customizable Display
Use Customize Units to show only the units you work with and hide the rest for a cleaner table.
Precision Control
Choose 2, 4, 6 or 8 decimal places, or Auto, to match shop-floor readability or precision engineering.
One-Click Copy
Copy a single result or every result at once in a clean format, ready to paste into documentation.
Unit Reference Guide
A built-in panel explains each unit's conversion factor and typical use, from kgf·cm servos to dyn·cm lab work.
Bidirectional Input
Type in either the from or to field and the other updates automatically, with a swap button to flip the pair.
Works Everywhere
A responsive layout runs on desktop, tablet and mobile, so you can convert at the bench or in the shop.
Frequently Asked Questions
How do I convert N·m to lb-ft?
Enter your Newton-meter value, set the source unit to N·m, and read the foot-pound (ft·lbf) row. For a quick mental check, multiply N·m by 0.7376 to get lb-ft, or multiply lb-ft by 1.3558 to get N·m.
What is the N·m to ft-lbs formula?
The conversion factor is 1 N·m = 0.737562 ft·lbf. So ft-lbs = N·m × 0.737562, and in reverse N·m = ft-lbs × 1.355818. The calculator applies these factors automatically with your chosen decimal precision.
How many ft-lbs are in 100 N·m?
100 N·m equals about 73.76 ft·lbf. Enter 100 with N·m as the source unit to see the exact value at your selected precision, alongside every other unit.
Is N·m the same as lb-ft?
No. Both measure torque, but a Newton-meter is the SI metric unit while a pound-foot (lb-ft, written ft·lbf here) is the imperial unit. One N·m is roughly 0.74 lb-ft, so the same fastener spec reads as a different number in each system.
How do I convert N·m to in-lbs?
Inch-pounds (in·lbf) appear in the Imperial group of the results table. One N·m equals about 8.8507 in-lbs. Enter your N·m value and read the in·lbf row, which is handy for small fasteners that are spec'd in inch-pounds rather than foot-pounds.
What is kgf·cm used for?
The kilogram-force centimeter (kgf·cm) is common in servo motor specifications for robotics and RC hobbies. It is the torque a one-kilogram weight produces one centimeter from the pivot. The Unit Reference panel notes this usage for each unit.
Can I use this for torque wrench settings?
Yes, it is ideal for translating torque-wrench specs between units. As with any reference, verify critical fastener values against the official manufacturer service manual before tightening.
How accurate are the conversions?
Conversions use internationally recognized factors and high internal precision. You can display up to 8 decimal places, which is more than enough for automotive work and engineering calculations.
