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.
All 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)
One second of latitude is equal to approximately 30.9 meters (101.4 feet) on Earth's surface.
how much distance on earth's surface does one second of latitude equal?
Although it varies slightly depending on your Latitude one second is right around 101 ft.
It works out to 101.16 feet. In the field, we use the rule of thumb of 100 ft.

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.
How far is a geographic second?
A geographic second is equal to one second of longitude at the equator, which is approximately 31.5 meters or 103.3 feet. This measure represents a unit of angular measurement rather than a fixed distance on the Earth's surface.
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?
To convert seconds of latitude and longitude into meters, you can use the following approximations: For latitude: 1 second of latitude is approximately equal to 30.87 meters. For longitude: 1 second of longitude is approximately equal to 30.87 meters at the equator, but varies depending on the latitude. You can use a formula like 30.87 meters * cos(latitude) to get a rough estimate at different latitudes.
How far is a second in latitude and longitude?
One second of latitude is equal to approximately 30.9 meters, while one second of longitude can vary depending on the latitude but is generally around 30.9 meters near the equator. However, this distance decreases as you move closer to the poles.
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.
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.

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
The phase ten meters per second squared describes the?
The approximate acceleration of a body in freefall near the earths surface due to earths gravitational pull. The object in freefall gains 9.81 meters per second for every second that elapses (ignoring air resistance).
What is the field strength at a distance one Earth radius beyond the surface?
The field strength at a distance one Earth radius beyond the surface is equal to the field strength at the Earth's surface. It follows an inverse square law relationship with distance, so it is the same provided that there are no other factors causing a change.
