To achieve accuracy in distance measurements, how should distances be expressed?

To achieve accuracy in distance measurements, it is important to express distances in a way that maintains sufficient precision for navigation and safety. Distance expressed to the nearest whole nautical mile is practical for many maritime operations because it simplifies calculations and communication among crew members. Nautical miles are specifically designed for use on the water, aligning distance with the curvature of the Earth, and using whole numbers makes it easier to interpret and manage distances during maneuvers, especially when quick decision-making is required.

This method of rounding can prevent confusion that might arise with more decimal points, particularly under operational conditions where clarity is vital. While greater precision, such as to the nearest hundredth of a nautical mile, may seem beneficial for detailed planning, it can complicate communication and decision-making in practical scenarios, particularly where distances are significant. Therefore, using whole nautical miles strikes a balance between accuracy and usability in everyday boating operations.
