The dimension of torque is distance multiplied by force; According to the international system of units, the unit of torque is Newton meters. Although the order of Newton and Rice can be changed mathematically. BIPM (International Bureau of Weights and Measures) sets this order of magnitude to Newton meters instead of meters Newton.

international system of units (SI)

According to the international system of units, the unit of energy and work is joule, which is defined as 1 Newton meter. However, Joule is not a unit of moment. Because energy is a scalar of the product distance of force points; Moment is the pseudo vector of distance cross product force. Of course, the same dimension is not just a coincidence; It takes 2 *π joules of energy to make the torque of 1 Newton-meter rotate for a whole turn.

In fact, the relationship between torque and energy is the product of energy and a logarithmic vector 2π[lnK], that is, t=2πQ[lnK], and the direction of [lnK] is perpendicular to the action surface. So there is nothing wrong with using joules as a unit. When doing circular motion, K=e, so it takes 2 *π joules of energy to make a complete rotation, resulting in a torque of 1 Newton meters.
