As the plates continue to press against one another, the ocean plate gradually sinks beneath the continental crust and re-enters the mantle. According to Live Science, the deepest known ocean trench is the Mariana Trench, located in the Pacific Ocean. It is approximately 1,500 miles long. The deepest portion of the Mariana Trench is the Challenger Deep, a narrow portion at the southern end, which is roughly 36,000 feet deep. The water temperature in this area is slightly above freezing.The world's ocean trenches remain largely unexplored due to the immense pressures at such depths.
These are computer measurements of the size of a folder, file, hard drive, etc. 1  A bit is a binary digit. 2  A byte is 8 bits. 3  A kilobyte (kB) is 1,000 bytes.  A megabyte (MB) is 1,000,000 bytes.
So one kilobyte is actually 1024 bytes, and 1024 of those is (1024 x 1024) 1048576 bytes. In short, one Megabyte is really 1,048,576 bytes. There is a difference of about 48 KB, which is a decent amount. If you have a calculator, you will notice that there is actually a 47KB difference.
