Chain To Nautical Mile (Ch To Nm) Converter

The Chain To Nautical Mile (Ch To Nm) Converter is a handy tool designed to help you easily convert measurements from chains to nautical miles. This is especially useful in navigation, surveying, and maritime activities where precise distance conversions are essential.

A chain is a unit of length commonly used in surveying and land measurement. One chain is equal to 66 feet, which is equivalent to 22 yards or approximately 20.1168 meters. It is a traditional unit that helps in measuring land areas and distances.

A nautical mile is a unit used primarily in maritime and aviation contexts to measure distances at sea or in the air. One nautical mile is exactly 1,852 meters or about 6,076.1 feet. It is based on the Earth’s circumference and is used internationally for navigation.

The conversion formula from chains to nautical miles is straightforward:
Nautical Miles (Nm) = Chains (Ch) × 0.000164579

This formula is derived from the relationship between the length of a chain and a nautical mile, allowing you to convert any measurement in chains to nautical miles quickly and accurately using this tool.
