Let me explain more.

Answer 10

The time, length, mass, amount of substance, electric current all have many units.
The SI unit can only have 1 unit of each. That means length can only have one SI units and so does mass, amount of substance, electric current.

For example mass can be in grams,kilograms, pounds, tons.

SI units as you can see from what you posted has to be kilograms.

Another example is that time can be in seconds, hours, minutes.
The SI unit for time would be seconds (Refer to the paragraph you posted).


So SI units for mass is kg.

Now try to find the SI unit for length.
