It has slightly different values in different places on the earth. It's
generally between 9.75 and 9.85 meters per second2 anywhere .
The acceleration due to gravity is greater at sea level.
The acceleration due to gravity at sea level at the equator is 32.25744 feet/second2 (983.2186 cm/second2)Formula for your own altitude:Acceleration Due to Gravity (cm/s2) at Altitude (h) = Acceleration Due to Gravity (cm/s2) at Sea Level - 0.3086hwhere h is the altitude in kilometers.
To calculate gravity at any altitude, you can use the formula: gravity at altitude = acceleration due to gravity at sea level * (1 - 2 * altitude / Earth's radius)^2. The acceleration due to gravity at sea level is approximately 9.81 m/s^2, and Earth's radius is roughly 6,371 km. Substituting these values will give you gravity at your desired altitude.
We need some numbers to start out with. Let's assume that the Earth's radius,from the center to sea level, is 4,000 miles, and that the acceleration of gravityis 9.80000 m/s2 at sea level.We'll also need . . . 200 feet = 200/5,280 = 0.03788 mileThe acceleration due to gravity is inversely proportional to the distance from thecenter of the Earth. So, at a radius that's 200 feet larger, it's[ 4,000/(4,000.03788) ]2 = 99.99811 percent of its value at sea level= 9.79981 m/s2 .If you weigh 200 pounds at sea level, then at 200 feet altitude you wouldweigh 199pounds 15.9394ounces . . . a full 0.0606 ounce less.
It is less. The equation for gravitation is Gm1m2/d squared where G is the gravitational constant, m1 and m2 are the masses of the two objects and d is the distance between them. With increasing distance, the force is less.

Earth's gravity @ sea level
This is the acceleration due to Earth's gravity measured at sea level. Should read 9.8 metres per second per second.

At an altitude of 40,000 feet (approximately 12,192 meters), gravity is slightly decreased compared to sea level, but the change is minimal. The acceleration due to gravity at this altitude is about 9.8 m/s², compared to approximately 9.81 m/s² at sea level. This represents a decrease of about 0.3%, which is not significant for most practical purposes.
Mass is measured in kg's, and gravity is measured by the acceleration of an object caused by gravity, at sea level (ignoring air resistance). This force can be converted into Newtons per kg. Earth's is about 10m/s/s (couldn't put a squared sign in), therefore is about 10N per kg.
The measurement of the pull of Earth's gravity on an object is represented by a specific force called 'weight.' Weight is calculated by multiplying an object's mass by the acceleration due to gravity (9.8 m/s^2 on Earth).
The value of g is referred to as the acceleration of gravity.It's value is 9.8 m/s^2 on Earth.That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s^2.
