The SI system is much easier to use when analyzing scientific data since conversions can be done very simply without having to remember ridiculous conversions with units in the American system like slugs, feet etc.
With the SI system the prefixes make converting any unit to another very easy. if you wanted to convert 4.13 in to miles you would need a calculator and have to know that there are 12 inches in a foot and 5280 feet in a mile, work out the dimensional analysis and come up with a slightly accurate number after losing much accuracy in your calculator, but with the si system, if you wanted to convert say .01241 mm to kilometers you just move the decimal place, in this case six places to the left. Giving .00000001241 km.
Scientific notation is handy when you have a very large or very small number like the answer to the last example, .00000001241 can be written in scientific notation as 1.2141 X 10^-8 meters
600.00001 = 6.0000001 x 10^2 but there is no benefit in writing this way.
The benefit of scientific notation is that a number can only be written one way when using it. 0.018 is written as 1.8 * 10-2.
There is no benefit to doing so but the result would be 2.29792 x 10^5
It reduces extremely large numbers to a more manageable format. For example, instead of writing 100,000,000,000,000 (100 trillion), you would express it as: 1 x 10^14 or 1E14
Ask yourself. Would you rather write this out in long hand? 234,000,000,000,000,000,000 ----------------------------------- Or this? 2.34 X 1020 -------------- Let alone adding, subtracting, multiplying and dividing the first long number.

1.98282 x 10^8 but there is no benefit to doing so.
There is no benefit to doing so but the result would be 2.29792 x 10^5
There is no benefit to doing so as the result is longer to write than the number itself! However, the result would be: 6.853429781 x 10^9

All scientific advances benefit mankind in someway.
everything without it life would be a maze with no exit or entrace
Poor countries can benefit from a limited amount of scientific technology. They do not have the resources to utilize higher levels of technology, but they can benefit from things that improve the quality of food production, health care, and sanitation.
