What is a nautical mile (UK)?

The UK nautical mile, historically known as the Admiralty nautical mile, is defined as exactly 6,080 feet or 1,853.184 metres.

How is the foot (US survey) different from the international foot?

The US survey foot is defined as 1200/3937 meters and was historically used in US surveying, differing slightly from the international foot.

Why convert UK nautical miles to US survey feet?

This conversion helps interpret older maritime distances recorded in UK units for integration with US land surveying and engineering data.

Tips & Best Practices

Ensure you understand whether your data uses the UK or international nautical mile due to slight differences in length.
Be aware that the US survey foot differs from the international foot, which may affect certain applications.
Use this tool mainly for historical data or legacy records rather than modern surveying standards.
Cross-check converted values with the original units when working on critical engineering or navigation projects.

Limitations

The UK nautical mile is slightly longer than the international nautical mile, which can cause discrepancies if mixed.
The US survey foot differs from the international foot, potentially leading to minor variations.
Conversions using this tool are primarily for historical data and less applicable to contemporary navigation or surveying.
Care is needed when combining data sets using different standards to avoid measurement errors.
