It took me a while to be easily able to convert satoshis to BTC in my head but I figured out a way for me to remember it and now I have it down pat.

I remember it as "trip zero ten k" in my head, or 3 zeros (000) before 10,000 (10k).

.00010000

That gives me a nice reference point right in the middle and was my "ahaa" moment. eureka..

Now I mostly find myself thinking of BTC as "a million satoshis" = .01, "ten million satoshis" = .1, or "100k sat" = .001

Now I like it this way and its the millibits/bits/bytes that confuses me.. Maybe I'm silly for thinking this way but it works for me..

Nothing has to change on a fundamental level, just the output display of wallets and sites. Most of them offer that option already. I do think Satoshi missed a trick there. It would've been far simpler to do it from minute one. Average human psychology isn't programmed for piles of zeroes at the front.

Prevention is always better....

Now (when price is not big), micro payments are not clear eg: $0.1 = 0.0002622
With big price, like 1 bitcoin is $10k, $1 = 0.0001 and $0.1 = 0.000001 all payments are going to be messy with more zeros.

I believe now itself we need shift to base unit satoshi as mBTC or uBTC are confusing to most of the peoples.

Yeah I'm doing the same. And if it becomes higher numbers I reverse the situation :

I'll say 0.1 bitcoin or 0.01 bitcoins and not 10000000 satoshis.

I don't think there is any need for changing bitcoin units: BTC & Satoshis are enough. If you pay a high amount, you refer to bitcoin, if you pay a low amount, you refer to satoshi... That's a all.

And if you really want you can use uBTC and mBTC but I find it confusing
