Nautical Mile
A nautical mile (NM) is a unit of distance used in aviation and maritime navigation. It is based on the Earth’s geometry and equals 1,852 meters or about 1.1508 miles. Because it relates directly to latitude and longitude, it makes charting courses across the ocean or sky more accurate for navigators.
Nautical miles work together with knots—1 knot = 1 nautical mile per hour—to measure travel speed at sea or in the air. Converting nautical miles to kilometers or standard miles is simple with a reliable converter.
Parsec
A parsec (pc) is a unit of length used in astronomy to measure huge distances between celestial objects. It equals about 3.26 lightyears, or 31 trillion kilometers (19 trillion miles). The name comes from “parallax arcsecond,” referring to the way astronomers calculate distances by measuring the slight shift of stars in the sky.
The parsec helps express distances that are far too vast for lightyears or kilometers. Converting parsecs to other astronomical units makes the scale of the universe easier to understand for scientists and space explorers.
