扭矩是一个用来描述扭转力的科学术语，它的单位是牛顿-米（Nm）。
Torque is the scientific term for turning force, and it is measured in newton-metres (Nm).
物理单位“牛顿”，是以物理学家伊萨卡牛顿命名的，一牛相当于一颗处于地球表面苹果因重力因素而所受力的大小。
The newton, named after the physicist Isaac Newton, is approximately the force exerted by gravity on an apple at the Earth’s surface.
在这一节中，我们暂时离开牛顿定律来讨论一下单位问题。
In this section we depart briefly from the subject of Newton's laws to discuss the question of units.
比如，质量单位千克，热力学温度开尔文，能量单位焦耳，电流强度单位安培，力单位牛顿等。
Such as kilogram of mass unit , Kelvin of thermodynamic temperature , Joule of energy unit , Ampere of electric current intensity and Newton of force unit and so on?
