SI units are more accurate than English system units
It depends on the science.Most science normally uses the SI (international system) - the same system which is used in most countries of the world in everyday life as well. Theoretical particle physics often uses another system, called the system of natural units, or Planck units. Many sciences use at least SOME non-SI units; for example, in particle physics, even if the SI is used most of the time, energies are usually expressed in eV. And in most areas of science, non-SI time units (i.e., units other than seconds) are used.
most of the world does SI so more people can understand with it in SI units

The SI unit for temperature is Kelvin.Kelvin = Celsius + 273Fahrenheit and Celsius are non SI units, however, Celsius is used in science as it is so easily converted to Kelvin.
In most of the world, everything that is measured, is measured in SI units. Time, distance, mass, weight, area, volume and so on.
So that we all understand what we are doing.
A magnitude is a number and so has no units.
The system was designed so that they would be consistent.
There is no SI units for lithium. SI units are used for measuring physical attributes so it would depend on what attribute: density, boiling or melting point, conductivity, etc you wished to measure.
The correct answer doesn't appear in the list of choices.Each of those three quantities CAN be describes in SI units.
It is the accepted world wide system for measurement by the science community.
Derived units do not have a single 'look'. They are produced from the base units of a measuring system such as the SI system.In the SI system there are seven base units which are;MetreKilogramSecondAmpereKelvinMoleCandelaAll other units are DERIVED units.For example the units for volume is the cubic metre and density is derived from the metre and kilogram. So density is kilograms per cubic metre in the SI system.
