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

∙ 10y agoThe units in the SI system are related to by factors or multiples of 10. Rather than have a new name for every multiple of factor, the use of prefices is much simpler.
Also, it means that calculations in derived units become simpler. For example 35 milligrams per millilitre is the same as 35 grams per litre and 35 kilograms per kilolitre.
The calculations for the above paragraph took a total of 0 seconds. Try that with ounce, pound, stone and fluid ounce, pint, gallon! Or without using prefices.

Which is Not an SI base unit secondKilogramdegree Celsius Matter?
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”.
What are SI units and how do you convert them to metric?
SI and metric are the same units.

How many SI units?
The SI has 7 base units. These units can be combined in an almost unlimited way to form other (derived) units. The Wikipedia article on "SI derived units" lists some examples.
