How do you convert degrees to distance?

How do you convert degrees to distance?

At the equator for longitude and for latitude anywhere, the following approximations are valid:

1. 1° = 111 km (or 60 nautical miles)
2. 0.1° = 11.1 km.
3. 0.01° = 1.11 km (2 decimals, km accuracy)
4. 0.001° =111 m.
5. 0.0001° = 11.1 m.
6. 0.00001° = 1.11 m.
7. 0.000001° = 0.11 m (7 decimals, cm accuracy)

How do you convert angle to length?

The length of an arc is is the radius r times the angle θ where the angle is measured in radians. For instance, an arc of θ = 0.3 radians in a circle of radius r = 4 has length 0.3 times 4, that is, 1.2.

How many meters are in a second of longitude?

30.87 meters
At 49 degrees north latitude, along the northern boundary of the Concrete sheet, an arc-second of longitude equals 30.87 meters * 0.6561 (cos 49°) or 20.250 meters.

What is the distance of 1 degree of latitude?

about 111 kilometers
One degree of latitude, called an arcdegree, covers about 111 kilometers (69 miles). Because of the Earth’s curvature, the farther the circles are from the Equator, the smaller they are. At the North and South Poles, arcdegrees are simply points. Degrees of latitude are divided into 60 minutes.

How do I measure a 30 degree angle?

A 30-degree angle is an acute angle….Construction of 30 Degrees Using Compass

1. Draw a ray AB.
2. With C as the center and without any change in the radius, draw an arc that cuts the semicircular arc at point D.
3. With C and D as the center, draw two arcs that intersect each other and label it as E.
4. Join the points A and E.
