# Newton to Tonnes (force) conversion

Does anyone know the conversion factor to go from a force in Newtons to a force in tonnes?

The only relevant information I could find was this site, which says "1 newton = 0.00010197162 tonne-force"

Is this correct?

Thanks

There's a difference.Tonne(s) is a unit for mass,while Tonne-force is a unit for force.

1Kgf=9.80665N

That's all u need to know.The rest is just metric prefix...

So, 1 KgForce = 9.806 65N

Since 1 tonne (or is it ton?) = 1000 kg, does this mean 1 Tonne-force = 9.806 65 * 103N?

That's right."Kgf" is an ancient unit for force,but the metric prefixes go way back.

TONNE...(not "ton"!!).

Thanks for clarifying the tonne-force issue.

However, my professor insists that tonne is for force, and ton is for mass.

Bull****!!

$$1 tonne=1,000 Kg$$
$$1 ton\sim 907 Kg$$

I'd like to second Dex. Your professor is utterly wrong. Ton is an imperial unit of mass, Tonne is metric.

I think this "ton" is a nice multiple of pound avoirdupoids.2000,maybe...?
