Distance between two places on the earth Calculator

Calculates the distance and azimuth between two places from latitudes and longitudes.

Calculation assumes that the Earth is a sphere with a radius of 6378km.
Input negative degree for west longtitude and south latitude.

    [1]  2021/10/01 22:39   Under 20 years old / High-school/ University/ Grad student / Very /
    Purpose of use
    Determine length of time for longwave regime (h/\lambda<<1)Tsunami to travel from Valparaıso, Chile to Hawaii. This modelling process has application in climate modelling and emergency response time which has vast implications for national security across the pacific. The authors would like to acknowledge this useful online tool, as well as funding secured from national grant no. 2.64 under the 2017 Climate SN Committee.
    [2]  2021/09/15 23:08   40 years old level / An engineer / Useful /
    Purpose of use
    Measure how far away do I live from the place I was born
    [3]  2021/08/30 21:47   Under 20 years old / High-school/ University/ Grad student / Very /
    Purpose of use
    Finding distance to place of birth (17,032 km!)
    [4]  2021/08/12 07:43   50 years old level / An office worker / A public employee / Very /
    Purpose of use
    Idle curiosity.
    [5]  2021/06/07 14:25   60 years old level or over / A retired person / Very /
    Purpose of use
    Determine the distance between two points using the same numbers for coordinates in both the Indian 1975 datum and the WGS84 datum. The difference would be the error in using the 1975 datum coordinates on a WGS84 map; or the correction necessary to make the 1975 coordinates "good" on a WGS84 map.

    Purpose of use
    How far away do you live from the place you were born?
    [7]  2021/04/05 18:45   30 years old level / An engineer / Very /
    Purpose of use
    Finding the answer to the question: "What is the farthest place you have traveled to?"
