Meter
A meter (m) is the base unit of length in the metric system and one of the most widely used measurements in the world. It is defined precisely by the distance light travels in a vacuum during a fraction of a second, making it highly accurate for scientific use. In everyday life, meters measure things like room dimensions, athletic tracks, and object heights.
Because the meter anchors the entire metric system, converting to centimeters, kilometers, or millimeters is simple and consistent. Unit converters make switching between systems—such as meters and feet—fast and reliable for any project.
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.
