Problem calculating distance between two points with Latitude and longitude

[tayusso]

Hi, im having some issues creating a new column that calculates the distance between two points.
I have the latitude and longitude of both points, created a new column to give me the kilometers between these two points but all i got is a 0 in return.

Below is the formula im using and a screenshot of the points i have.

KM =
var x1 = RADIANS(SELECTEDVALUE(DMS[LAT OR]))
var x2 = RADIANS(SELECTEDVALUE(DMS[LAT DEST]))
var y1 = RADIANS(SELECTEDVALUE(DMS[LON OR]))
var y2 = RADIANS(SELECTEDVALUE(DMS[LON DEST]))
var R = 6371
var lcos = ROUND(SIN(x1)*SIN(x2)+cos(x1)*cos(x2)*cos(y1-y2),15)
var arco = ACOS(lcos)
return
arco*R

Hi tayusso. Nice to meet you. I wonder if you have found a solution to this problem:

I have the same problem and I can't find a solution.

In a column, if you write the number directly inside the ACOS() function it returns a correct answer, like this: Distance = ACOS(0.896494) = 2.924,31 Km

Could you help me please?

This is a column, so you should not use SELECTEDVALUE

The formula you wrote would work great in a measure, but not in a column. The column should be:

KM = 
var x1 = RADIANS(DMS[LAT OR])
var x2 = RADIANS(DMS[LAT DEST])
var y1 = RADIANS(DMS[LON OR])
var y2 = RADIANS(DMS[LON DEST])
var R = 6371
var lcos = SIN(x1)*SIN(x2)+cos(x1)*cos(x2)*cos(y1-y2)
var arco = ACOS(lcos)
return
arco*R

Although using a measure would be much better for memory if you increase your table size.
