What is the relationship between mu and kg?

It doesn't matter. μ is the unit of area and kilogram is the unit of mass. It is impossible to compare the two. If we force them to compare, it will be a joke that Guan Gong beat Qin Qiong. Therefore, the two can not be compared, nor can they be converted to each other.

Mu: (quantity) drawing unit. Ten equals one acre; One hundred acres equals one hectare. Current city mu. One acre equals sixty square feet; 115 hectares.

Kilogram: the unit of mass of the basic unit of the international system of units, equal to the mass of the original international kilogram preserved in Seyfel, France. Also called kilograms.

unit of measure

Refers to a scalar defined and adopted by convention, and any other similar quantity can be compared with it, so that the ratio of two quantities can be expressed by a number. The unit of measurement has the name and symbol given according to the agreement.

All kinds of physical quantities have their own units of measurement, and the number of selected substances displayed under specified conditions is the standard of basic units of measurement. The choice of basic quantity can be different in different periods and disciplines. For example, in physics, seven physical units, such as time, length, mass, temperature, current intensity, luminous intensity and quantity of matter, are taken as basic quantities, and their unit names are seconds, meters, kilograms, kelvin, amperes, Candeira and moles.
