And now we now why the GIS/Tax Assessor folks can't seem to get it right.

They must be using international feet;-)

Kidding aside; that may be correct if the program is converting from grid to surface (of course, why not convert the SqFt first).

LOL - That's one county over from me. I gave the Assessor a call to let him know that they goofed. He said they had grabbed that tool elsewhere and failed to QC it before making it available.

What a bunch of maroons!

Everybody knows the correct conversion figure is 1320.

Makes you wonder if their "Tax Tool" also might need to be checked.

The government's "Tax Tool" is always checked, calibrated and ready to be deployed whenever a citizen bends over 🙁

What a bunch of maroons!

I couldn't stand not knowing how they got this so wrong, so I grabbed the source code for their page. Here's the section that does the calculations:

function areaCon() {
var a1 = document.conv2.area1.selectedIndex;
var a2 = document.conv2.area2.selectedIndex;
var a = document.conv2.areaval1.value;
document.conv2.areaval2.value;

if (a1 == 1 && a2 == 1) {document.conv2.areaval2.value = a;}
if (a1 == 1 && a2 == 2) {document.conv2.areaval2.value = Math.round((((a) * 0.000023)) * 100000) / 100000;}

if (a1 == 2 && a2 == 1) {document.conv2.areaval2.value = Math.round((((a) * 43559.458316)) * 100000) / 100000;}
if (a1 == 2 && a2 == 2) {document.conv2.areaval2.value = a;}

I was taught that the conversion from Sq. Ft. to Acres is Sq. Ft./43560=Acres. Apparently their programmer thought 1/43560 rounded to six decimal places (0.000023) was a sufficient substitute.

Their conversion factor for acres to sq. ft is 1 acre=43559.458316 sq. ft. I'm not sure how they arrived at this factor, but I bet it involved more careless math and probably a few assumptions.:-P
