Improve Bitcoin Amount Units and Readability #10243

Issue

Bitcoin uses a very large number of decimal places. For anything less than 1 bitcoin, it is difficult for users to comprehend the amount they are looking at. People are not good at thinking about numbers more than 2 decimal places smaller than a whole number. Especially when commas or other group separators are not traditionally used for fraction digits.

Proposed solution

A discussion on IRC #bitcoin about which units an exchange used triggered me into thinking... why not use a bitcoin format similar to what is used with Latitude and Longitude?

41°25'01.123"N and 120°58'57.456"W

Comparison of current and suggested format

Instead of: 1.54321098 btc Format as: 1.543m210u98s btc

The wonderful thing about this format is that you are always using units of "BTC", but at the same time you are also displaying units of mBTC, uBTC, and satoshis!

A small bitcoin amount like: 0.00001098 btc Could instead be formatted as: 10u98s btc

Aren't people even worse when it comes to milli, micro, nano etc? Personally, when I look at the number 10u98s, at first glance I have no idea what it represents because I've never seen it before. I may struggle with 0.00001098 too but at least I'm familiar with the concept of decimals.

If you want to display units of mBTC, uBTC and satoshi perhaps using a color representation makes a bit more sense:

This concept is similar to tones in Mandarin Chinese:

Adapting geographic coordinate system would make things harder and weirder for all users. Also for readability, there are already mBTC and satoshi.

This is more of a social issue and not a software issue. If a certain convention is widely used we'll happily add it to the software. I'm sure developers of other wallets feel the same.

This isn't a good place to discuss it, though.
