In a pinch it's easier to reason that since 2^10 = 1024, 2^11 = 2048, and 1626 lies between those two numbers, log_2 1626 is a bit more than 10.
Memorizing powers of two is useful for lots of quick mental estimation!
- Taek 9y ago12 words of 1626 characters is almost exactly 128 bits, which is what is typically accepted as cryptographically secure. We added a checksum though and then grabbed 256 bits instead of 128, so the numerical alignment no longer applies sadly.
