Currently, the way the mass of a black hole is measured is indirectly determined by the speed of its rotation and/or its gravitational influence.
Note: Theoretically, the faster a black hole rotates, the more massive it is. The gravitational influence is estimated by the diameter of the event horizon (or even as the difference between the spherical edge of the event horizon and the edge of the oblate diameter of its ergosphere).
Also the latest consensus is that there is not a relevant relationship between the observable size of the accumulated bulge about the Black Hole and the size of the Black Hole itself.

Do Black holes suck in all Matter?
No; I am not in a black hole yet.A black hole, like any other object with mass, will attract objects that are near by.No; I am not in a black hole yet.A black hole, like any other object with mass, will attract objects that are near by.No; I am not in a black hole yet.A black hole, like any other object with mass, will attract objects that are near by.No; I am not in a black hole yet.A black hole, like any other object with mass, will attract objects that are near by.
How do they measure the mass of black holes?
The mass of a black hole can be calculated by observing the movement of any object which is in orbit around it - or simply close enough to be affected by the black hole's gravity. The same method can be used to calculate the mass of other objects - for example, both stars in a binary star system.
What becomes of energy when it is sucked up into a black hole?
Such energy has a mass equivalent (m = e/c2). Any such mass falling into the balck hole will increase the mass of the black hole.
What would happen if a black hole entered your solar system?
A lot would depend on the mass of the black hole. A black hole the mass of an asteroid (should any of that size exist) would probably enter the Solar System and get back out again, just like any comet. We might not even notice it. A black hole the mass of a star would probably cause a lot of disruption in the orbits of the planets.A lot would depend on the mass of the black hole.

What would be your weight in deep space and near a black hole?
Your "weight" is the magnitude of the gravitational force between you and another mass. -- In deep space, far from any other mass, the gravitational force between you and any other mass would be very small, but never zero. -- Near a back hole, the gravitational force between you and the black hole would be (gravitational constant) x (your mass) x (black hole's mass)/(your distance from the black hole)2
How does a black hole wrap the space-time fabric?
Any mass will warp space and time, according to the General Theory of Relativity. In a black hole the mass is simply more concentrated.Any mass will warp space and time, according to the General Theory of Relativity.

When a black hole collaspes does its mass decrease?
As far as we know, black holes cannot collapse any further. However, if a star were to collapse and form a black hole, its mass would be the same.
What is inside of a black hole?
All the matter that collapsed into the black hole, as well as any matter that fell into the black hole after the initial collapse. The only distinguishable part of such matter is its mass - any structures of matter, even atoms, get destroyed.
Why is the gravity of the black hole so large?
The gravity of an object depends on its mass, and on the distance to the object. In a black hole, the mass is concentrated in a very small space. That means that IF YOU GET VERY NEAR the black hole, the gravity will be enormous. But at any given distance, the gravity of a black hole will not be larger than the gravity of any other object of the same mass.Also, note that some black holes have a huge mass - in extreme cases, more than ten billion times the mass of the Sun. In that case, the huge gravity is due to the huge mass.
Is there any way to get rid of black holes?
No. Anything you put into a black hole simply gets added to its mass.
How many star can form a black hole?
The death of any star greater than about 5 times the mass of our Sun is likely to result in a black hole.
Does a black hole have mass?
No, a black hole definitely does not have infinite mass. In some mathematical models, there is an object called a singularity, inside a black hole, which has infinite density. That is not the same as infinite mass. If a finite mass is contained in zero volume, then the density becomes infinite. We do not have any real confirmation that such a thing as a singularity or an infinite density actually exist, but they may.
