About Nautical Miles
A nautical mile (nmi) is equal to 1,852 meters or approximately 1.15078 statute miles, based on one minute of arc along Earth's meridian. This unit is the standard for maritime and aviation navigation worldwide because it directly relates to Earth's geometry, making navigation calculations simpler. Ships and aircraft measure speed in knots (nautical miles per hour). The distance between parallels of latitude is almost exactly 60 nautical miles. International maritime law uses nautical miles to define territorial waters and exclusive economic zones.
About Inches
The inch (in) is a unit of length primarily used in the United States, Canada, and the United Kingdom. Historically, an inch was defined as the width of a man's thumb, but today it's precisely defined as 2.54 centimeters. Common examples include: a quarter coin is about 1 inch in diameter, a standard smartphone is roughly 6 inches tall, and most computer screens are measured diagonally in inches. The inch is divided into fractions like 1/2, 1/4, 1/8, and 1/16 for precision measurements.
