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.

FranAll 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)

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.
