Prefixes make it much much easier to understand. The prefix tells how many digits the unit has. So it is both easy to convert and understand. :)
Example:
1 gigabyte is easier to read than 1000000000 bytes
Because they indicate the relationship of the unit to the base unit
10
Prefixes are useful when describing SI units because they allow for easy conversion between different units of measurement by indicating a multiple or fraction of the base unit. This helps to express quantities in a more manageable and standardized way.

Actually neither are official SI units — neither of the two “gallons”, imperial or US the units of length are organized in units of 1000, one metre is subdivided into 1000 milimetres and i kilometre is 1000 metres. A centimetre as 10 mm and one hundredth of a metre is related to SI units of length, but it is not SI. However it is useful when I’m doing woodwork which is more than I can for whatever “gallon”.
SI and metric are the same units.
International System of Units (SI)
The principal SI units used to derive all other SI units are the base SI units. These are the units for physical quantities such as length, time, mass, electric current, temperature, amount of substance, and luminous intensity.

SI units are more accurate than English system units
When SI units combine, they create derived SI units that are used to express physical quantities. These derived units are formed by multiplying or dividing the base SI units. Examples include the Newton (kg*m/s^2) for force and the Pascal (N/m^2) for pressure.
