How much distance on earth's surface does one second of latitude equal?

The circumference of the earth is very nearly equal to 40,000 km. In the meridional direction ie north-south it is almost exact, so the distance from equator to pole (north or south) is 10,000 km. In fact that is the definition that was adopted for the meter originally, though now we have a standard meter which is very slightly different to 1/10000 of the equator to pole distance.
For your purpose take it as 10,000 km. Then in terms of latitude, this is divided into 90 degrees each degree having 60 minutes, each minute having 60 seconds. So the total number of seconds of latitude is 90 x 60 x60 = 324,000. so 1 second of latitude will be 10,000/324,000 km, or 10/324 km. Putting this into meters we get 10,000/324 meters,
which comes to 30.86 meters.
So 1 second of latitude = 30.86 meters, or in feet = 101.2 ft.

∙ 12y agoAll longitudes converge at the north and south poles, so the distance represented
by any change in longitude depends on where you are with respect to the equator
and the poles.
One second of longitude corresponds to 101.36 feet along the equator, and
zero distance at the poles.
In between, it's
(101.36 feet) x cosine (your latitude)

Wiki User
∙ 14y agoAlthough it varies slightly depending on your Latitude one second is right around 101 ft.
Wiki User
∙ 12y agoIt works out to 101.16 feet. In the field, we use the rule of thumb of 100 ft.
Wiki User

What distance is represented by one second of latitude. 60 minutes for each degree?
one minute of latitude is approximately 1.15 miles (1.853 km). You can just divide that by 60 to get the distance for one second and multiply 60 to get 60 minutes.
What is latitudes distance?
Latitude is how far something is North or South of the Equator.

How do you calculate seconds of latitude and longitude into meters?
At the equator 1° of latitude or longitude is equal to about 111 kilometers (69 miles). This remains the same for latitude (north-south) measurements, but the longitude lines get closer together as you move poleward.
How far is a second in latitude and longitude?
1" in latitude represents a distance of about 102 feet. 1" of longitude represents a distance of about 102 feet along the equator. The farther from the equator you are, the shorter 1" of longitude becomes. At the north and south poles, all longitudes converge in one point.
What distance in metres on the ground is the equivalent of one second of arc in longitude or latitude?
One minute of arc as measured at the centre of the Earth covers one nautical mile on the surface of the Earth at mean sea level. One nautical mile is 6080 feet or 1853.2 metres. Therefore one second of arc would be 6080 / 60 = 101.3 feet or 30.886 metres. Lines of latitude are at regular intervals parallel to the equator. The relationship between degrees of latitude and the distance spanned on the earths surface remains constant. Therefore at all latitudes 1 minute of latitude spans 1 nautical mile on the earths surface. Lines of longitude converge at the poles. Therefore the relationship between degrees of longitude and the distance spanned on the earths surface is reduced as the poles are approached. At the equator the distance spanned by 1 minute of longitude would be 1 nautical mile. At the poles it would be zero. To calculate the actual distance on the surface of the earth between two points of known latitude and longitude requires a knowledge of spherical trigonometry to calculate the great circle distance between the two points. The distances quoted are for the surface of the earth at mean sea level. Distances will be increased above sea level and reduced below it.
Acceleration due to gravity at earths surface is?

What is the importance of 9.81 in accelaration due to gravity?
9.81 is the acceleration due to the force of gravity experienced by bodies on or about the surface of the earth (nominally at sea level) the units are meters per second / per second, that is to say a stone dropped from a height will gain 9.81 m/s velocity for every second it falls (is in freefall) however , if you move from the earths surface , this figure will diminish, an example being : if you double your distance from the earths centre you will experience 1/4 of the acceleration (or force) you experienced at the surface
Can you use the distance formula to find the distance between two points on a map?
yes you can. It will represent longitude and latitude. Take the longitude and latitude from the first point and from the second one place the values in the formula you get the distance.

What covered most of earths surface at the beginning of the second era?
Warm, shallow seas covered much of Earth's surface during early Paleozoic time.
What are seismic waves that reach the earths surface and travel outward?
the one with the most damege is the surface wave because they are on the surface of earth. but p-waves are the second and s-waves are the third

What is the field strength at a distance one Earth radius beyond the surface?
I assume you mean, of the gravitational field? The gravitational field is inversely proportional to the square of the distance. At a distance of 1 Earth radius, the distance from the center of the Earth is twice the distance at the Earth's surface; thus, the field strength is 1/4 what it is on the surface. If at the surface the field strength is about 9.8 meters per second square, divide that by 4 to get the field strength at a distance of one Earth radius from the surface.I assume you mean, of the gravitational field?

The phase ten meters per second squared describes the?
