Hello, I have two coordinates that a respondent reported: * A: 32.780491, -96.847283 * B: 32.764811, -96.831151 So, maybe x1 = 32.780491 y1 = -96.847283 x2 = 32.764811 y2 = -96.831151 Are there any ways to calculate the distance between these two points, and record the value of distance (perhaps in miles) for Qualtrics embedded data? Thank you very much in advance.

Hi @jhwang ,You can use Math operation to do this.
