How do you convert from longitude to meters?

How do you convert from longitude to meters?

Subtract the smaller longitude from the larger one for places that are both in the Eastern or both in the Western Hemisphere. Add the longitudes if the places are in different hemispheres. Multiply the degrees of separation of longitude and latitude by 111,139 to get the corresponding linear distances in meters.

How do you determine longitude?

Longitude at a point may be determined by calculating the time difference between that at its location and Coordinated Universal Time (UTC). Since there are 24 hours in a day and 360 degrees in a circle, the sun moves across the sky at a rate of 15 degrees per hour (360° ÷ 24 hours = 15° per hour).

How long is an arc second?

An arcsecond (denoted by the symbol “) is an anglular measurement equal to 1/3600 of a degree or 1/60 of an arcminute. There are also 206,264.5” in a radian, so that 1” = 4.848 ×10-6 radians.

How to calculate the distance between two latitudes?

This tool calculates the straight line distance between two pairs of latitude/longitude points provide in decimal degrees. Additionally, this tool will convert your decimal coordinates to degrees minutes seconds (DMS).

Is the degree, minute and second of latitude the same?

A degree, minute or second of latitude remains fairly constant from the equator to the poles; however a degree, minute, or second of longitude can vary greatly as one approaches the poles (because of the convergence of the meridians).

How much does one degree of longitude cover?

One-degree of longitude equals 288,200 feet (54.6 miles), one minute equals 4,800 feet (0.91 mile), and one second equals 80 feet. Illustration showing longitude convergence. Latitude distances remain constant.

How much is length in meters of 1° of latitude?

Length in meters of 1° of latitude = always 111.32 km Length in meters of 1° of longitude = 40075 km * cos (latitude) / 360
