0.00000001 = satoshi
0.00000010 = dekatoshi / dekasat
0.00000100 = hectoshi / hesat
0.00001000 = kiltoshi / kilosat
0.01000000 = megatoshi / megasat
we may not need the first 2 after 1 satoshi.
it is always easier to say 10 satoshi and 100 satoshi instead of deka and hecta satoshi in my opinion.
you can say the same thing for 1000 but kilo is a bit different, it is used more often and more people understand what "kilo" means than those who understand what deka and hecta mean.
