What distance corresponds to one degree of latitude along any meridian?
Answer
60 NM
Explanation
A minute of latitude is approximately one nautical mile, so one degree—60 minutes—is approximately 60 NM. This relationship is used to measure north–south distance on charts. **Key takeaway:** One degree of latitude is approximately 60 NM. **Glossary:** **Meridian**: A line of longitude running between the poles; **nautical mile (NM)**: A unit corresponding approximately to one minute of latitude.
