Ok, I just created a lightning invoice for 250k sats and the prefix is 2500u

I guess I found a mistake in the book

In this case, we can see that this payment is for the mainnet instance of the Lightning Network (lnbc), and is requesting 2,500 uBTC (microbitcoin), or 25,000,000 satoshis.

I mean, micro-something is something times 10^-6 so 1 uBTC is 100 satoshis:

So 2,500 uBTC should be 250,000 satoshis, no?

What am I doing wrong? Please help, I think I'm stupid

Isn't [this](https://github.com/lnbook/lnbook/blob/develop/15_payment_requests.asciidoc#the-human-readable-prefix) wrong?

Aren't 2,500 uBTC 250,000 satoshis?

I mean, micro-something is something times 10^-6 so 1 uBTC is 100 satoshis: 

```
>>> 100_000_000*(10**-6)
100.0
```

So 2,500 uBTC should be 250,000 satoshis, no?

```
>>> 2500*100_000_000*(10**-6)
250000.0
```
