The nautical mile in the United Kingdom, as in most countries, follows the international standard, which is approximately equal to 1.852 kilometers or 1.15078 statute miles (land miles). This international standard for the nautical mile is used for maritime and aviation navigation in the UK, as well as in many other countries around the world.
To provide some context, the nautical mile is based on the Earth's circumference and is defined as one minute of latitude along a meridian. It is commonly used in navigation because it provides a consistent and convenient way to measure distances at sea and in the air, where latitude is an essential factor. The use of the international nautical mile ensures compatibility and consistency in maritime and aviation operations across different regions and countries.
A "finger" is a traditional unit of length used for measuring cloth or fabric. Similar to the span, the finger is based on the width of a human finger. It was historically used in various countries, including England.
In England, a finger was typically equal to about 2.25 inches or approximately 5.715 centimeters. However, like other traditional units of measurement, the precise length of a finger could vary depending on the region and historical context.
