Arc2Meters Converter

Convert arc seconds to meters or meters to arc seconds at a specified latitude

Earth is not a sphere and therefore the calculation is only a approximation valid at sea level.

Enter Meters:   or Arc-Seconds:

Enter Latitude:

m
km
arc-seconds
arc-minutes
degrees

 

1 degree° = 60 arc minutes '
1 arc minute ' = 60 arc seconds ''
1 arc second '' at equatorial sea level = 1852m/60 = 30.86666667m

Formlua: cos(degree latitude) * (1852/60)
Example   0° latitude and 1 arc second:   cos(0) * 30.866666667 = 1 * 30.866666667 = 30.866666667
Example 45° latitude and 1 arc second: cos(45) * 30.866666667 = 0.7071067811865476 * 30.866666667 = 21.82602931286047
Example 60° latitude and 1 arc second: cos(60) * 30.866666667 = 0.5000000000000001 * 30.866666667 = 15.433333333500004
