Calculates the distance between two points in degrees, radians, miles, or kilometers. This uses the Haversine formula to account for global curvature.


  • from Coord origin point
  • to Coord destination point
  • options Object Optional parameters (optional, default {})
    • options.units string can be degrees, radians, miles, or kilometers (optional, default 'kilometers')


var from = turf.point([-75.343, 39.984]);
var to = turf.point([-75.534, 39.123]);
var options = {units: 'miles'};
var distance = turf.distance(from, to, options);
var addToMap = [from, to]; = distance; = distance;

Returns number distance between the two points
