This converter allows you to convert chains [ch] to fathoms [fm.] or fathoms [fm.] 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.
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.
