In physics, a newton metre is a compound unit of torque corresponding to the torque from a force of 1 newton applied over a distance arm of 1 metre.

Some people, as a matter of convenience, have opted to use a gramatical contraction of these units that is outside of the traditional SI vernacular. Instead of saying Newton-Metre, these people will, in casual conversation, refer to torque in units of the "Newtre".
