If you are talking about Newtons and Newton-meters, its not just a matter of "two different systems", like inches and feet, two different measurements of length. They measure two different things. Its like asking for a conversion between grams and liters - two different things. Newtons are units of linear force. Newton-meters measure torque, better understood as "rotary force". Check reference sources for more information.

Yep, realise that that's why I asked what additional information would be required... any help would be much appreciated. Cheers

OK, this is basics - Think of N-m like lbs-ft - this is how torque is measured. For example - a one ft long torque wrench and you apply 10 lbs of force to it. This will apply 10lbs-ft or torque to the fastener or whatever. N or Newtons is another unit of force in imperial units one would use pounds or lbs. If you stand on a weight scale and you weight 160 lbs this would convert to N by multiplying 160 pound by 4.4482216 to get Newtons. In summary - there is not an equation to simply convert N to N-m. These are not compatable units as you need a distance component.

Yep, I understand all that... I guess what I'm looking for, and maybe my thread title isn't asking the right question, but I have a measurement in Newtons and I'm assuming this measurement in force is required in a formula, with additional information, to calculate Newton Meters for torque. I know it won't be a straight conversion... so my question should actually read 'what is the formula for calculating Nm'

Force * Distance = Torque The "additional information" you are looking for is the perpendicular distance from the center of rotation to the centerline of that force.

the answer is stated right there in your question. the force is newtons and the distance is meters...kunk
