The 9.81 m/s^2 of gravity, the same as you feel standing on the ground. However, if you mean acceleration relative to the ground, by definition, having reached its terminal velocity, that one has to be zero.

As everyone else has already said, the acceleration of an object that has reached terminal velocity is zero.
If you were wondering about the object's velocity, then you would have to measure the exact amount of air resistance it creates. This is because the only thing slowing an object's acceleration is the resistance of the atmosphere.
If you don't take the air resistance into account (or there wasn't any, like in a vacuum chamber), then the object would continue to accelerate towards the center of the Earth at 9.8 meters per second squared (m/s/s) until it went SPLAT on the Earth's surface. Since there wouldn't be anything to completely stop the acceleration, it wouldn't have a terminal velocity.

Terminal velocity, by definition means it cant go any faster, the force of gravity has affected the object based on its density to the point where it is traveling as fast as it can against air resistance and other factors. It would retain a constant speed (in a perfect simulation) and there fore with out a decrease or increase, its acceleration must be zero.

Things accelerate until they reach terminal velocity, and when they reach it, they stay the same speed, thus their acceleration at terminal velocity is ZERO.

There is no more acceleration after you reach terminal velocity

The acceleration due to friction acts upward and the acceleratin due to gravity acts down ward.
When their magnitudes become equal,the net acceleraion is zero.
The body attains the terminal velocity.

0 terminal velocity pretty much means it quits accelerating

At constant Velocity ACCELERATION is ZERO.

zero. it's not accelerating @ terminal velocity (well, roughly).

You want to know the actual speed? - cuz that would depend on the object
