Explain bits versus nats as you would to a capable student, in 3-4 sentences.

**Bits** and **nats** are both units for measuring information, just like inches and centimeters both measure length. A **bit** uses base-2 logarithms (log₂), so it tells you how many yes/no questions you need to identify something—for example, picking one option from 8 equally likely choices takes log₂(8) = 3 bits. A **nat** uses natural logarithms (ln or logₑ), which is often more convenient in calculus and probability theory since derivatives work out cleaner. They're related by a constant conversion factor: 1 nat ≈ 1.443 bits, so you can easily convert between them depending on which is more useful for your problem.
