I suggest you search for some examples to get the general idea. Basically, you convert all units to generic descriptions such as [length], [time], [current], etc.; then you combine them. If you add a length to another length, you get a length again, so:
[length] + [length] = [length]
Similarly,
[length] - [length] = [length]
Please note that:
1) This is different from regular addition or subtraction.
2) You can't add or subtract different types of units. For example, if in a formula you are supposed to add a speed and an acceleration, you get:
speed + acceleration
= [length] / [time] + [length] / [time]2
... which can't be added. If you get something like this, something is wrong with this formula. Such formulae might be used as "rule-of thumb" formulae, and might sometimes give good approximations - but they are not dimensionally correct.
On the other hand, if you multiply or divide units in a calculation, you get the regular product or quotient, for example:
[length] times [length] = [length] squared.
Dimensional analysis
Dimensional analysis is important because it allows us to check the consistency of equations by ensuring that the units on both sides of the equation are the same. It helps in deriving relationships between physical quantities and simplifies problem-solving by reducing the number of variables involved. Additionally, dimensional analysis can be used to convert units and provide insight into the underlying physics of a problem.

How do you change metric units?
The process of writing units of each variable in a real-life problem is called dimensional analysis or unit analysis. It is useful for understanding the real-life problem and for checking to see we get a valid answer. Please see the links for additional explanations.
dimensional analysis is very simple method for convert the one system of units into another system of units. And we can check the correctness of the equations. We can show the relations between physical phenomenal quantitatively.VALI
a way to analyze and solve problems using the units, or dimensions, of the measurements.
It is not necessarily the most appropriate way. A proper understanding of the way in which different measurements are related is sufficient - without going into dimensional analysis. Dimensional analysis can be useful for people who have not got their heads around the relationships between units.
This technique is usually called dimensional analysis.
Dimensional analysis is a method in physics and engineering used to check the correctness of equations by examining their dimensions, or units of measure. By ensuring that the dimensions of physical quantities on both sides of an equation are consistent, dimensional analysis can help identify errors and verify the relationships between different variables. It is a powerful tool for understanding and deriving equations in science and engineering.
Unless I am very mistaken, dimensional analysis indicates that it cannot be done.
