This converter allows you to convert chains [ch] to nautical miles [NM] or nautical miles [NM] to chains [ch]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 chain [ch] ≈ 0.0109 nautical miles [NM]1 nautical mile [NM] ≈ 92.0624 chains [ch]

Convert chains to nautical miles

There are two simple ways to convert chains [ch] to nautical miles [NM]. In the first calculation method, the value in chains [ch] is divided by the rounded conversion factor of 92.0624. The second method multiplies the value in chains [ch] by the rounded conversion factor of 0.0109.

  • Nautical miles [NM] ≈ chains [ch] ÷ 92.0624
  • Nautical miles [NM] ≈ chains [ch] * 0.0109

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of chains [ch] to nautical miles [NM] can be achieved using the following calculation method.

  • Nautical miles [NM] = chains [ch] ÷ 1,852 * 20.1168

Convert nautical miles to chains

Converting nautical miles [NM] to chains [ch] is easy and can be done in two ways. The first method involves multiplication, in which the value in nautical miles [NM] is multiplied by the rounded conversion factor of 92.0624. The second variant is a division. Here, the value in nautical miles [NM] is divided by the rounded conversion factor of 0.0109.

  • Chains [ch] ≈ nautical miles [NM] * 92.0624
  • Chains [ch] ≈ nautical miles [NM] ÷ 0.0109

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of nautical miles [NM] to chains [ch] can be achieved using the following calculation method.

  • Chains [ch] = nautical miles [NM] * 1,852 ÷ 20.1168
