A naming method that uses the concept name of quantity as the unit name

A naming method that uses the concept name of quantity as the unit name is a naming method in which the unit name is

unit system name + concept name of quantity + "unit"

For example, the name of a unit in the universal system of units is

universal length unit
universal time unit
universal speed unit
universal mass unit

This method has various drawbacks.

1. Naming all dimensional units makes it difficult to detect errors using dimensional analysis.
# For example, it is better not to name units of speed.

2. If you don't know the conceptual names of quantities, you won't know the unit names.
# There will be a huge number of names to remember, and they will not necessarily be related.

3. The conceptual names of quantities that are closely related are similar to each other, making it difficult to abbreviate the units.
# It is cognitively better for the abbreviations of units of closely related quantities to be different.

4. When there are multiple natural units for the same quantity, it becomes unclear what the unit names refer to.
# For example, circular angle and radian.

I think that problem 1 is particularly problematic [1].

It is quite difficult to explain this in English.

Looking at cases like this, it seems that even if the units to be named are limited, there are still people who "don't understand".
