Well, Misbah hit it 111m. How do the TV people calculate the distance exactly ?

They have each field calculated to the boundary and then do a computer mapping thing.
This technology hasn't been around long.
I vaguely remember a six that cleared Adelaide Oval stands at the long end of the ground ... who was that? Rod Marsh perhaps, Viv Richards? That would have to be 150 metres +

I think It is calculated by same mechanism, by which a Hawk Eye calculates the trajectory of a ball going towards the stumps.
Once you could recreate the trajectory of a cricket ball (which with so many cameras on ground is not a difficult thing nowadays), getting the actual distance is not difficult. of course, like hawk-eye or calculating the speed of a delivery it would also have some margin of error, but for all practical purposes these values are reliable.

They use a simple laws in Physics known as laws of Projectile motion. They calculate the speed of the Ball when it leaves from bat by Radar (speed gun) its angle of elevation, thus from simple linear equation the length of a six can be determined. As you know, the object thrown in air at the angle of 45 degrees, travels the maximum distance.

The Cricket ball has a sensor built in it, and a Sensor by the Stumps, Hence the sensor senses how far the ball has traveled away from the stumps. Otherwise they cant measure the distance with accuracy of within meters > 111 m <

During the matches, I have seen some stats like 'Speed of the ball when it left the bat" - I don't know how the hell they calculate it. So, if they have a way to calculate the angle to then it's simple parabola equation.

This is simple they use the "projectile motion" graph to estimate the length,Remember the graphs they show for fours ,Along with the elevation and exact spot where the ball landed,the same coordinates they apply here and take assumption of the "projectile motion".

The length from the pitch to the entire boundary perimeter is pre-calculated and the local staffs measure the rest with a meter tape.
that's it.

They have devised some mechanism to measure the distance the ball travelled before it landed such as measuring the speed of the ball bowled.

its basic maths.... first they record the speed of the ball when it leaves the bat (ofcourse by using the speed gun which they use to measure bowler's bowling speed)... then they record the time (in seconds) from ball hitting the bat to ball falling on ground... by simple equation distance=speed*time.... we get the distance
