The "league" unit in distance has the numbers of a nautical league. If Azgaar want to clarify the current one, already on the program has the numbers of a nautical league, the text could be updated to:

    function toKilometer(v) {
      if (unit === "km") return v;
      else if (unit === "mi") return v * 1.60934;
      else if (unit === "lg") return v * 4.828;
      else if (unit === "vr") return v * 1.0668;
      else if (unit === "nmi") return v * 1.852;
      else if (unit === "nlg") return v * 5.556;
      return 0; // 0 if distanceUnitInput is a custom unit
    }

and the HTML like:

          <div data-tip="Select a distance unit or provide a custom name">
            <div>Distance unit:</div>
            <select id="distanceUnitInput" data-stored="distanceUnit">
              <option value="mi" selected>Mile (mi)</option>
              <option value="km">Kilometer (km)</option>
              <option value="lg">League (lg)</option>
              <option value="vr">Versta (vr)</option>
              <option value="nmi">Nautical mile (nmi)</option>
              <option value="nlg">Nautical league (nlg)</option>
              <option value="custom_name">Custom name</option>
            </select>
          </div>

The "league" unit in distance has the numbers of a nautical league. If Azgaar want to clarify the current one, already on the program has the numbers of a nautical league, the text could be updated to:

      if (unit === "km") return v;

      else if (unit === "lg") return v * 4.828;
      else if (unit === "vr") return v * 1.0668;
      else if (unit === "nmi") return v * 1.852;
      else if (unit === "nlg") return v * 5.556;
      return 0; // 0 if distanceUnitInput is a custom unit
    }

I would like to suggest the following refactor of the toKilometer Function for possibile expansions in the future :

    function toKilometer(v) {
      switch(unit) {
      case 'km': return v;
      case 'mi': return v * 1.60934;
      case 'lg': return v * 4.828;
      case 'vr': return v * 1.0668;
      case 'nmi': return v * 1.852;
      case 'nlg': return v * 5.556;
      default: return 0; // 0 if distanceUnitInput is a custom unit
     }
    }

No break; is needed as we return in every line. I would say this is easier to read.

I don't see how it's better. If with earlier exit can be simpler than switch.

Azgaar, what's your decision on this added code? Current commit only has nautical mile and proposed edits on comments are:

• Change current league to nautical league as 5.556 appears to be nautical.
• Create league with 4.828 as conversion factor for land league.

Also, do we put the switch or the list of else ifs?

[Azgaar]

It's fine, you can add. The code should be like that:

    function toKilometer(v) {
      if (unit === "km") return v;
      if (unit === "mi") return v * 1.60934;
      if (unit === "lg") return v * 5.556;
      if (unit === "vr") return v * 1.0668;
      return 0;
    }

Else is not required as we are returning value immediately.

I'm ok to merge, please update the version

@Avengium, hm, not that way. Now there is a conflict. Also need to update hash for changed scripts in index.html.
