One second of latitude corresponds to about 30 meters on the surface of the Earth.
To elaborate, the Earth's circumference is approximately 40,075 kilometers (or 40,075,000 meters), and there are 360 degrees of latitude, with each degree containing 60 minutes, and each minute containing 60 seconds. So, one degree of latitude is about 111 kilometers (or 111,000 meters), and one minute of latitude is about 1.85 kilometers (or 1,850 meters). Therefore, one second of latitude is approximately 30 meters.
