Petameter

A petameter (Pm) is a unit of length in the metric system, equal to 1 quadrillion meters (1 petameter = 10¹⁵ meters). This unit is extremely large and is used mainly in astronomy and theoretical physics to describe vast distances, such as those between stars or galaxies. For example, one petameter is about 105.7 light years. Since it measures such enormous distances, the petameter is not used in everyday life or common scientific applications—it’s mostly used in discussions about the scale of the universe.

Nautical Mile (UK)

The nautical mile (UK) is a unit of distance used primarily in maritime and aviation navigation in the United Kingdom. Traditionally, it was defined as 6,080 feet (about 1,853 meters), which is slightly longer than the modern international nautical mile of 1,852 meters. This UK definition was used before international standardization in 1929. Today, the international nautical mile is widely adopted, but the UK nautical mile historically played an important role in navigation and mapping.
