## How do you find the radius using latitude and longitude?

Moving along a circle of latitude means moving along a small circle. A circle of latitude at latitude lat=1.3963 rad has the radius Rs = R · cos(lat) = 1106 km, so d=1000 km now corresponds to an angular radius of rs = d/Rs = d/(R · cos(lat)) = 0.9039.

## How do you convert latitude and longitude to Miles?

As such, it is easy to convert latitude into miles. Divide the amount of miles by the degrees in a circle. The circumference of the earth along the equator is 24,901.92 miles, and there are 360 degrees in a circle. This results in about 69.2 miles.

**What is the formula for longitude and latitude?**

Distance

Haversine formula: | a = sin²(Δφ/2) + cos φ1 ⋅ cos φ2 ⋅ sin²(Δλ/2) |
---|---|

c = 2 ⋅ atan2( √a, √(1−a) ) | |

d = R ⋅ c | |

where | φ is latitude, λ is longitude, R is earth’s radius (mean radius = 6,371km); note that angles need to be in radians to pass to trig functions! |

### How do you calculate distance using latitude?

If you treat the Earth as a sphere with a circumference of 25,000 miles, then one degree of latitude is 25,000/360 = 69.44 miles. A minute is thus 69.44/60 = 1.157 miles, and a second is 1.15/60 = 0.0193 miles, or about 101 feet.

### What is the distance between two longitude?

The distance between longitudes at the equator is the same as latitude, roughly 69 miles. At 45 degrees north or south, the distance between is about 49 miles (79 km). The distance between longitudes reaches zero at the poles as the lines of meridian converge at that point.

**What distance is 1 degree of longitude?**

54.6 miles

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.

#### How far is a geographic minute?

One degree of latitude equals approximately 364,000 feet (69 miles), one minute equals 6,068 feet (1.15 miles), and one-second equals 101 feet. 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.
