9.80665 m/s^2
Depending on where you are on the earth's surface the acceleration of gravity can vary by about 0.1 m/s^2. The average on earth though is taken to be 9.80665, in physics calculations 9.81 m/s^2, 9.8 m/s^2, or even 10 m/s^2 are often used.
Note: 10 m/s^2 is actually a fairly good approximation and can speed up calculations significantly.

What is the weight of 1800 milligrams?
Convert this to kilograms, then multiply with the gravity (9.82 meters per square second). The result will be in Newtons.Convert this to kilograms, then multiply with the gravity (9.82 meters per square second).

What is the unit of acceleration measured in kilometers per hour?
Kilometers per hour is used to measure speed, not acceleration. In SI, the acceleration is commonly measured in meters per square second.Kilometers per hour is used to measure speed, not acceleration.

What is the centripetal acceleration of an object being swung on a string with a radius of 5 meters at a velocity of 4 meters a second?
Use the formula a = v2 / r, with v = velocity (speed, actually) in meters/second, r = radius in meters. The answer will be in meters per square second.
How fast is a skydiver after falling 3 seconds if they accelerate at 10 meters per second?
The acceleration is expressed in meters per second square, which really means (meters / second) / second. Every second, the skydiver will be 10 meters per second faster than the previous second. Therefore, after 3 seconds, he will have a speed of 30 meters per second.
What quantity is calculated as the inverse of speed?
If speed is calculated in meters per second, the invers (reciprocal, actually) would be seconds per meter. I don't believe there is a special name for that. Some of the more commonly-used units have special names, like "Newton" for force, but not every unit has its own name. For example, square meters are just called square meters, and the units for speed (meters per second) and acceleration (meters per second square) are called just that, and don't have any special names.If speed is calculated in meters per second, the invers (reciprocal, actually) would be seconds per meter.
