How to find the distance between two locations

How to find the distance between two locations

* Latitude and Longitude are measured with degrees

ACOS( SIN(lat1*PI()/180)*

SIN(lat2*PI()/180) +

COS(lat1*PI()/180)*

COS(lat2*PI()/180)*

COS(lon2*PI()/180-lon1*PI()/180) ) * 6371000

[I used this formula to check the distance between two locations when I created a Field Mobile PowerApps]
