But not nearly as interesting seeing the big number. Also, who is that supposed to be clear to? The raised numbers are so small I can't even read them on my phone.
Not really. Most people aren't familiar with scientific or engineering notation. Writing £1,000,000, one million pounds or £1Million is a lot clearer than writing £1×10^6.
It's not about the size of the number, it's about presenting information in a way that the average reader can understand. The best way to do that is to present it in the way that they're accustomed to and I don't think I've ever seen scientific notation used to refer to a sum of money.
It's great that you and I understand scientific notation, but it's worthlesss when you're trying to get the average person to understand what you're writing if they don't know it themselves.
To make myself clear, I'm not saying that scientific notation isn't useful, I'm just saying that most people don't understand it.
