There exist also E24, E48 and E96 series. In electronics, particularly at the beginner's level, we start with certain postulates such as 'take a single transistor, and bias it from a 12v supply with 1mA collector current so that its collector sits at half the supply voltage'. So instead of ending up with, for instance, 6.1K we could start with 4K7 and work from that. But, as a manufacturer, everytime I introduce another item on to a parts list, that's another part for stores to count out, for production to insert, for inspection to inspect and for the testers to check. There is a price to be paid for every extra part on the parts list for the product.
Most people seem to be OK with resistors, but capacitors also cause consternation.
I guess we in 'the rest of the world' have a bit of advantage because we have decimalised,, so we tend to ge used to Kilogrammes, millimeters, centilitres and similar. So you won't find use using deci or centi as a prefix, they are 'only' 10 and 100 divisors. The list shows the commonest prefixes. Note that the multipliers all have capital single letters, the divisors all have lower cases. Each prefix is 1000 times larger than the one below it, or 1000 times smaller than the one above.
