太阳的旋转周期是，26天，地球是一天，最后把一切转化成，米千克秒的单位，得到旋转动能的数据。
Well, the sun rotates about its axis in 26 days, the earth in one day, and so I finally convert everything to MKS units and I find these Numbers for the rotational kinetic energy.
现在我们已经把单位确定了-，有了米，秒、千克-，我们可以开始测量了。
So now that we have agreed on the units — we have the meter, - the second and the kilogram — we can start making measurements.
在物理学研究中除了国际单位制外，其它如厘米•克•秒和米•千克•秒单位制也使用。
Aside from the si system, other systems such as CGS and MKS are in use in the study of physics.
如果我们以国际单位制或米—千克—秒单位制中各种单位之名称的形式来考虑的话，相当数量的人被包括了。
If we think in terms of the names used for various units in the International, or meter-kilogram-second, System, a fair number are involved.
我们是通过电的单位和量纲来表示电场的单位和量纲的，如果我们把真空的电容率定义为无量纲的量，请用基本力学量米、千克、秒来表示电荷的量纲。
Express the unit and dimension for the electric field in terms of unit and dimensionality of charges, if we take the permittivity of the empty space as dimensionless quantity.
