Decimeter (dm): The decimeter is equal to one-tenth of a meter (0.1 meters). It is used less frequently than other metric units but can be encountered in certain applications.
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.
