how many kgs make a newton metre?

Question

to use a torque wrench the setting has to be 13kgs but the wrench is only in newton metres? what is the new setting?

Answer 1

This is kind of like asking how many seconds in a mile. hmmmm...double check that there isn't a Nm somewhere you are missing.

To get Nm, you have to take 13kg x 9.81 x L where L is the length of the lever arm (wrench length).

m

Answer 2

Mukluk is right.

This is a very strange scenario but considering the fact that you have 13 kgs, you'll have to measure the length of the lever arm. A standard torque wrench would be about 0.250m. Make sure you measure in metres NOT inches or millimetres.
Then go: 13 x 9.81 x length (metres)

And there you have it... Torque.
Cheers.

Answer 3

Torque wrenches execute a moment/torque, so the units of a torque wrench are (Force) x (Length), such as Newton meters (N)(m) or (lb)(ft).

13 kgs is not a torque, but rather a mass.

A mass of 13 kgs on Earth will exert a (13kg)(9.81m/s^2) = 127.53 kg m/s^2 = 127.53 N force due to gravity.

Answer 4

Newton metres is torque and kg is mass. The setting should be given in Nm, not kg. Are you sure it doesn't say 13Nm?

Answer 5

A Newton is (kg m)/s/s

A Newton meter would be (kg m^2)/s^2

Answer 6

as above
