Convert chains to fathoms

There are two simple ways to convert chains [ch] to fathoms [fm.]. In the first calculation method, the value in chains [ch] is divided by the rounded conversion factor of 0.0909. The second method multiplies the value in chains [ch] by 11.

  • Fathoms [fm.] ≈ chains [ch] ÷ 0.0909
  • Fathoms [fm.] = chains [ch] * 11

The calculation method with a rounded conversion value is more suitable for rough conversions from chains [ch] to fathoms [fm.], as the calculation result may contain rounding errors. Therefore, the variant with the exact conversion factor is more suitable.


Convert fathoms to chains

Converting fathoms [fm.] to chains [ch] is easy and can be done in two ways. The first method involves multiplication, in which the value in fathoms [fm.] is multiplied by the rounded conversion factor of 0.0909. The second variant is a division. Here, the value in fathoms [fm.] is divided by 11.

  • Chains [ch] ≈ fathoms [fm.] * 0.0909
  • Chains [ch] = fathoms [fm.] ÷ 11

The rounded conversion value can cause rounding errors, resulting in inaccurate calculation results. To ensure that the conversion from fathoms [fm.] to chains [ch] produces the most accurate calculation result possible, the conversion should be performed using the exact conversion factor.
