incorrect geodeticLengthOperator geodeticArea Operator measurements in imperial units.

[LefterisKoumis]

I am using the example as posted here to calculate the geodetic length and area of a location. Wanted to use imperial units (ft and miles).

So, I changed

const geodesicLength = geodeticLengthOperator.execute(line, { units: "kilometers" });
const planarLength = lengthOperator.execute(line, { units: "kilometers" });


const geodesicArea = geodeticAreaOperator.execute(polygon, { units: "square-kilometers" });
const planarArea = areaOperator.execute(polygon, { units: "square-kilometers" });

to:

const geodesicLength = geodeticLengthOperator.execute(line, { units: "miles" });
const planarLength = lengthOperator.execute(line, { units: "feet" });

const geodesicArea = geodeticAreaOperator.execute(polygon, { units: "square-miles" });
        const planarArea = areaOperator.execute(polygon, { units: "square-feet" });

Then I noticed that the geodetic measurements were way off incorrect

Then I changed the "units" to "unit" for geodetic measurements 

const geodesicLength = geodeticLengthOperator.execute(line, { unit: "miles" });
const planarLength = lengthOperator.execute(line, { units: "feet" });

const geodesicArea = geodeticAreaOperator.execute(polygon, { unit: "square-miles" });
        const planarArea = areaOperator.execute(polygon, { units: "square-feet" });

and now I get correct results!!

I don't see anywhere in the documentation stating to use unit instead of units for geodetic measurements.
